Design and Implementation of Reliable Wireless Sensor Networks- A Case Study in Commuter Trains

Abstract: This paper describes the design and implementation of a wireless sensor network in a commuter train environment. First, we analyze the applications the sensor network is used in, which is then used to propose a solution specifically designed for train applications. The solution introduces a number of measures into the communication protocol of the sensor network meant to increase the reliability of the communication between the different nodes of the network. These measures will be implemented and tried out in practice in an actual train environment to evaluate their effectiveness.
