An Algorithm of Minimum Energy Multicast Based on Network Coding

Network coding is a hot research field currently, many scholars use network coding to improve the wireless network throughput, reduce network energy consumption and enhance network lifetime. The issue of energy consumption of wireless multi-hop network is extremely vital because of the limited energy reserve of each node. Unlike the existing paper to solve energy consumption problems of the methods used, in this paper, for the first time used in wireless multi-hop networks to build butterfly structure and similar structures to reduce the multicast method to solve the energy problem. More importantly, this paper uses a random topology, the source node and destination node is randomly assigned, which makes the algorithm has a wide range of adaptability, proposed Network Coding based Multicast algorithm. In addition, the algorithm is relatively simple, can be any of the existing network coding based multicast algorithm transformation, thereby significantly reducing energy consumption.
