Introduction

AB Pty. Ltd is a delivery company that has 6 trucks to deliver their wide range of products for the third parties. They have their set delivery zone to cover the entire Austin downtown, Texas, USA. A truck on an average can delivers 5 times a day. However with expanding demand a truck can run only 3 times per day. Therefore the company is concerned about the delivery system to get updated soon so that maximum product delivery coverage per day can be possible with their existing number of trucks. The company is now planning to upgrade their existing delivery system with the following:

• Development of Smart App to simulate the truck movement
• Use of NODE-RED function node
• Creating a visual dashboard using NODE-RED that will have a speed Gauge and a speed chart of specific car

The smart app is going to be developed in order to simulate the connected vehicle and this will be done through Bluemix. Bluemix is a cloud platform that is developed by IBM. It does support to provide services and integrated DevOps to design, build, run, implement and manage applications on the cloud. Bluemix is actually based on Cloud Foundry open technology.

• Cloud Computing services with Bluemix

It is a type of internet based computing that perform several services including servers, storage and applications. These services are delivered on the organisation’s device and computers through the help of internet. Thereby the applications and the services provide to the company are being accessed by the service provider via web itself instead of any hard drive. The services delivered are used by t he cloud customers.

Cloud Computing Standards

The cloud computing services are offered by companies like IBM’s Blue cloud technology. It is based on the open standards and open source software that could link the computers of the system all together.

Problem Description

The company is recently facing huge discrepancies in terms of delivery of order on time. And hence the customers are unsatisfied regarding the deliveries. The ever expanding demand of product delivery has led the company facing the issue of delayed delivery and long queue of pending delivery. As a result currently their trucks could deliver only 3 times per day instead of 5 times a day.

Possible Solution

The solution can be provided with the help of software application. This application is going to track the delivery vehicle status. As a result it will update in the system on the spot and hence the delivery vehicle can be instructed as per the current status detected via the application. This will save huge amount of time and increase accessibility.

Aim

The purpose of the project to create a cloud based simulation environment using IBM BlueMix for smart application design in clod environment in order to run the delivery vehicles efficiently.

Objectives

To analyse a business problem

To deploy a cloud based application to simulate the problem

To design a Node-RED based visual tool to debug telemetry data from simulation

Project Plan

The project focuses on the development of the software application. The focus of the project is based on the development of smart application for the company so that they can easily track their delivery vehicle status. The facility is provided by IBM BlueMix to design the application. Apart from that a strong database is also designed in order to keep record of the status as per the date and time. AB Truck scheduling system is going to be set for the handling of different products and connect them via the smart vehicle application.

Bluemix Smart app development and Telemetry

The task is carried out by deploy and extend an Internet of Things (IoT) application on Bluemix. It enables to simulate and manage vehicle location and driving status. The task is proceeded with IoT starter kit for connected thing and followed by download the starter source code given with this assignment to configure, and deploy a cloud based smart/ IoT (Internet of Things) application to simulate the business case. In this project a smart application is designed with cloud based IoT and Geospatial analytics. The vehicle kit consists of a vehicle simulator, html5 applications to manage vehicles on a map and the geospatial analytics service on Bluemix along with Node-RED for analytics.

From the organization dashboard’s device page, Device type is created and a unique device ID is entered. There after the next page show the credentials of the device. Similarly other devices can be connected with their credentials. 

The source code for the IoT starter kit is stored in the IoT-vehicle-geospatial-starter-kit project on the DevOps services. Following the instructions will allow creating a ZIP file of the code and downloading it to the PC.

1. Click EDIT CODE from the IoT-connected-vehicle-starter-kit project.
2. Highlight the root of the source tree and click File -> Export -> Zip from the menu and save the downloaded file locally. Extract the Zip file.
3. Open the manifest.yml.file and enter the name for the host and name
4. Open config/settings.js. This file stores the device and the API key configuration data.

• For iot_deviceType, enter vehicle.
• For iot_deviceOrg, enter your six-character organization ID (for example, O4ze1w).
• For iot_deviceSet, enter the ID and tokens for the three devices you registered.
• For iot_apiKey, enter the API key you created.
• For iot_apiToken, enter the API key token.

These are the configuration parameters that are used by the Geospatial analytics service.

Save the change

From the root directory of the extracted application, type cf login and follow the prompts, enter https://api.ng. Bluemix.net is used for the API endpoint and collect Bluemix ID email address and password as login credentials. Type the cf push to Bluemix to deploy the application. After the deployment of the application, run the map app at https://app-name.mybluemix.net. The simulated vehicles can be seen across the map. 

Now by clicking any vehicle the telemetry data can be viewed. The 6 trucks of the company can be simulated in the similar manner and the count of the trucks can be controlled by Bluemix environment variable: VEHICLE_ COUNT. 

Step 4. Building analytics with Geospatial analytics service

Using the Bluemix Geospatial Analytics service, each of the vehicles can be tracked when vehicle enters or leaves a defined geofence region. The created Map app interacts with the service, and enables to simulate graphically.

Click ADD A SERVICE in the Bluemix dashboard. Choose Geospatial Analytics from the service catalog. Plan of Free is selected and clicks CREATE to bind the service to the application.

The starter-kit application includes APIs to start and stop Geospatial Analytics with the configured IoT Foundation organization. The service can be started through https://app-name.mybuemix.net/GeospatialService_start and wait for the page to show the success notification within 30-40 secs.

Now geofence is created using the Map app. Alert button is created on the toolbar to start the geofence creation process. After that by dragging the edges geofence is positioned. Geofence is created by click on the center black circle. 

Geospatial analytics service adds up this geofence to the listed watched regions and publish the MQTT message through the IoT Foundation whenever the assigned trucks of the company enters or leaves the area. Also a geofence can be deleted by selecting the region and click DELETE.

Step 5. Tester App

Instructions are sent through command in the Tester App. It was done to simulate the vehicle to change its properties like state and speed.

1. Open the Map app and the Tester app side by side to view them simultaneously.
2. On the bottom form of the Tester app, a vehicle is selected and its ID is entered. Then the speed of the vehicle is set to a value 100 and click Update property. The setProperty API can be used to dynamically change a custom property of the delivery vehicle.

To delete the property, update the property with an empty string so that the delivery vehicle will stop including the property in its telemetry message.

Step 5. Tester App 

Step 6. Creating Node-RED analytics application

Node-RED is a visual tool. It s used in this case yo wire together logical events in IoT. in Bluemix is used in order to extend the starter kit. It is extended with basic analytics.

1. Implement the Node-RED application in Bluemix by clicking ADD APPLICATION using Bluemix dashboard
2. After the application is in running mode, BIND A SERVICE is clicked and followed by choosing IoT service created in Step 1.
3. After this, Node-RED canvas is opened at https://node-red-app.mybluemix.net/red/.
4. An ibmiot input node is dragged from the canvas. Then a Debug node is dragged to the right side of ibmiot node. Wire the two nodes. Double-clicking the ibmiot node the configuration is build as follows:

Select Bluemix service -> from input type select device event -> for device type enter truck -> For device Id select check box -> for event, enter telemetry -> for format, enter json -> for name, enter telemetry

Select the debug pane and click Once the configuration is set up and the starter kit application is running, it can be seen for the connected vehicles in the debug pane:

The telemetry data for each of the individual vehicle for VEHICLE_COUNT vehicles are shown in the single array. In order to change the filter for the single vehicle, a function is added as a function node in the middle of the flow, followed by double clicking and fill with the given code:

var data = msg. Payload;

for (var i in data) {

if (data[i].id = “ABC – 2”) {

msg.payload = data [i];

return msg;

Hence the telemetry information is collected by the debug system of the simulation through Bluemix app service. The information collected in the form of geospatial data were helpful to decode the business problem and find suitable solution in the form of upgraded digitised delivery system.

Justification

IBM Bluemix cloud platform has helped tremendously to solve the company’s delivery issue. With Bluemix cloud platform, it was possible to explore the existing through simulation technique and drive the business scenario with application and its service. It is data rich software and through the help of this app, it could possible for the company to manage all their entire delivery services through their digital channel. The entire system that was created was cloud based and thus enabled to provide the geospatial services through the Map app provided by Bluemix. Through the simulation technique, the delivery vehicle scenario was able to identify and steps were taken to upgrade the entire system of the delivery company as per their current requirement.Risk

To enable the service the entire delivery system of the company was analysed and thus the existing scenario is simulated using Bluemix platform. This required performing the basic service enable process through Bluemix which was not a simple task to perform. Since the connection building process was extremely time taking and thus the applications were often not responding.

However with the gradual trial method, link could be able to build among the service provider and the actual business scenario to control the delivery vehicle properties. The procedure that was explained in the step by step process could give a clear indication that how the function was performed using command and addressing table at a core level. The logical sequence of the app procedure was maintained while performing the task of connectivity one by one.

The Map app has to be enabled before that in order to access and link the geospatial service along with Bluemix smart app development procedure.

The geospatial service was not that easy to link with the app service. In order to access the service the entry and the exit of the delivery vehicle has to be tracked through map app in Bluemix. Thereby the characterization of geofence technique was also mentioned in the step by step process.

Conclusion

Cloud computing service through Bluemix was a enormous guidance by the system service for the delivery company. It provided huge opportunities to optimise the existing application and making the entire system of delivery vehicle more efficient. In terms of business value the platform was extremely scalable and cost-effective. The geospatial service and the telemetry option in the Bluemix made the delivery system traceable at any point of time. Also the system of delivery vehicle has become more productive. The properties of the delivery vehicles such as speed and state could also be changed as per the change in system directly with the service provider.
