A novel network-coding-based retransmission mechanism using chase combining mechanism for broadcast flows is presented. An information-theoretic performance bound is also developed to explain and predict the coding gains of the chase combining (CC) in network coding broadcast scheme using random coding bounding techniques. The core idea is to recover packets for individual receiver simultaneously...
An iterative joint decoding algorithm for data gathering wireless sensor networks is proposed in where the correlation between sensorspsila data is considered as a global code and iterative decoding is performed by concatenating the global decoder with the decoder of error correcting code applied to encode sensors observations. We apply this algorithm for sensor networks with binary CEO model where...
