Introduction

Designed to enable vehicular communication through wireless sensors

The mechanism will aid in reducing the likelihood of accidents in case of visibility issues during extreme weather conditions

This system will help a certain vehicle detect all the vehicles in the entire network formed by wireless sensors

The system will be available as a platform so that other applications may be built using it

Devices Used

IRIS Wireless Measurement System 2.4 Ghz mote module were used

Several hours of readings were recorded to study the patterns of RSSI

The algorithm estimates the distance of a certain sensor when provided by an RSSI value

With slight modifications, this algorithm has the flexibility to execute on other kinds of wireless sensors

StarNode Algorithm - Overview

The StarNode algorithm is capable of localizing all the nodes in the entire network

This algorithm provides an accurate estimate of distances between each node

Assumption: each vehicle will be equipped with a StarNode (consisting of three wireless sensors set in a particular orientation)

One StarNode has the ability to detect the distance & direction of another StarNode

StarNode Algorithm - Working

The algorithm first estimates the distance of a particular node (in the range of the StarNode)

Once the distance of all the nodes in the range are estimated, the algorithm assumes another node as the origin of the first StarNode, and calculates the relative distances of all the other nodes

The specific orientation of StarNode enables the wireless sensors to detect the direction of the other node

A set of recursive equations is used to track all the nodes in the network

Benefits

The framework will be available for other developers to build various applications over it.

Several tools such as RStudio and Processing can be used with this framework

One of the applications of this framework is vehicular communication

It provides an interface between hardware and software
