Abstract: Existing loss recovery techniques are developed mainly for static Wireless Sensor Networks (WSNs) which cannot be directly applied for mobile sensors networks. Developing a loss recovery and error control technique for Mobile Wireless Sensor Networks (MWSNs) is a challenging one due to the mobility of nodes. It involves huge amount of overheads in terms of additional bits added and hence consume more energy. In this study an error control technique for loss recovery is proposed for cluster based MWSN. Each Cluster Head (CH) or Forwarder Node (FN) encodes the data and transmits to the selected forwarder node which in turn will decode and retransmit it to the sink. Based on the channel error probability, Low Density Parity Check (LDPC) code and multipath encoding techniques are adaptively applied. Simulation results show that the proposed technique reduces the packet drop and energy consumption.
