We propose a new method for encoding information in wireless sensor networks. In addition to forwarding packets, routing nodes mix (i.e. code) packets from different sources to increase the information content for each transmission to neighbor nodes. We investigate the improvement in network throughput/lifetime via simulation programs. We implement the new method on different wireless sensor network...
We devise an adaptive fault-tolerant scheme based on the exponentially weighted moving average (EWMA) which can provide fault tolerant in sensor networks and balance between traffic overhead and transmission failure. We use the multipath routing to transmit packets, and according to wireless network environments we adaptively change the required number of paths for transmission. So it can achieve...
