Multicast algorithm in wireless sensor networks based on distributed networking coding

Aiming at the shortage of network source consumption and load balance in traditional shared tree multicast algorithm, this paper takes the network coding into account and puts forward a new shared tree multicast route protocol based on network coding. This algorithm adopts the method of minimum link consumption to select the node, and realizes the data transfer from multi-source nodes to multi-destination nodes. Simulation results show that with the technology of network coding, the consumption of wavelength resource and network resource can effectively reduced.
