METHOD OF RANDOM NETWORK CODING IN WIRELESS SENSOR NETWORK

摘要

A random network coding method of a wireless sensor network is provided to transmit data by confirming whether a network coding method is applied in the node of wireless sensor network. A sensor node determines an adjacent node showing beacon signal to a transit node(S301). The sensor node confirms by transmitting data index information(S302). The sensor node determines whether a network coding method is applied(S303). The sensor node listens secretly data of the other sensor node through the opportunistic reception. The sensor node applies the network coding mode. And the normal transmission mode is applied(S305).
