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
