Description
Summary:In Wireless Sensor Network, packet failure or error is to be controlled possibly. Based on that, we presented Cross-layer Based Error Control Technique for WSN in our previous work. In this paper, we present Modified relay node selection and corruption aware method for further improve the performance of the network. Modified relay nodes are selected using Markov chain decision process. Three relay selection methods are discussed in this paper. Those methods are “permanent”, “reactive”, and “adaptive”, which have various mandates for relay update. After the relay node selection, data packets are transmitted to the destination by selecting these relay nodes. At the receiver, the received data packet is verified whether it is corrupted or not using Received Signal Strength Indicator. If the received packet is corrupted, then the corrupted packet is encoded before re transmission using Low Density Parity Check Codes. Simulation results show that performance of this work is superior to our previous work in terms of delivery ratio and packet drop.
