Aiming ate the disadvantage of network resource and load balance, this paper analyses the traditional multicast routing protocol base on tree, and then puts forward an improved multicast routing protocol based on network coding and existing distributed shared tree. It adopts minimal link to select the node and puts forward the algorithm of node selecting… (More)
Aiming at poor channel reliability and topology dynamic variation in the wireless sensor network transmission. Based on the existing error correction algorithm, a new improved error control mechanism is proposed in this paper based on network coding, and the simulation experiment also shows its feasibility.
