Abstract: An efficient broadcast transmission scheme based on intra-flow and inter-flow network coding in delay tolerant mobile sensor networks (DTMSN) was proposed. In the scheme, the sink nodes transform the original broadcast data into coded packets by utilizing random linear network coding, and then forward them to sensor nodes. Sensor nodes exchange the coded packets by employing an optimized opportunistic network coding algorithm. Once receiving enough independent coded packets, the sensor nodes can decode them and obtain the original broadcast data from the sink node. Analysis and simulation show that the scheme can further reduce broadcast delay and network cost than those schemes only based on random linear network coding.

Key words: delay tolerant mobile sensor networks, broadcast transmission, network coding, random linear network coding, opportunistic network coding
