Abstract:

A partial network coding scheme is proposed for wireless sensor network based on the eventdriven, it can meet highefficiency, lowpower transmission in the case of partial nodes participating in the encoding. The encoding nodes are categorized into the business encoding nodes and capability encoding nodes based on the heterogeneity of sensor nodes and the eventdriven way, increasing the robustness of the network coding and improved the efficiency of network coding. Simulation shows that this scheme is superior to the traditional network coding scheme in energy consumption, network throughput and transmission delay.

Key words: wireless sensor network, partial network coding, business encoding node, business encoding node
