A Reliable Relay Multicast Method Based on Network Coding in Wireless Ad Hoc Networks
Problems for designing reliable transmission strategy in Ad hoc networks must be considered because the nodes are usually run in battery operated with limited energy,the higher wireless link reliability failure,etc.This paper presents a reliable relay multicast method based on network coding,this method allows part of the receivers playing the role of the source in the form of relaying,to perform the task of transmission to other receivers with higher link failure.Theoretical analysis and numerical results show that the proposed method is feasible,and to some extent improves the Ad hoc networks for multicast transmission,extends the network lifetime.
