In this paper, an energy-efficient multicast routing algorithm in multi-hop wireless networks is proposed aiming at new generation wireless communications. Different from the previous methods, this paper targets maximizing the energy efficiency of networks. In order to get the optimal energy efficiency to build the network multicast route, our proposed method tries to maximize the network throughput and minimize the network energy consumption by exploiting network coding and sleeping scheme. Simulation results show that the proposed algorithm has better energy efficiency and performance improvements comparing with the existing methods.
Multicast routing technology of Ad hoc network is a method of transferring specific data to a group of clients selectively; therefore, quality of the services is the key to evaluate the method. After the analysis of energy model and other routing algorithms ,an energy model and a balanced energy network multicast routing algorithm EBAMRA have been proposed in this article,. Experiments had been done, the simulation results show that this algorithm is feasible and effective, which provides a new and effective way of Ad hoc multicast routing technology.
A HIP multicast mode; based dynamic multicast routing algorithm (HIPDMR) was brought out and network model was established to describe and simplify problem to be researched. HIPDMR used Bellman-Ford as routing search algorithm, which can determine dynamic multicast routing with minimum hop number and overhead while meet constraints of bandwidth, delay, jitter and packet loss rate. Simulation experiments result show that HIPDMR can build dynamic multicast routing under constraints of multiple QoS comparing with algorithms that not considering QoS assuming network node output link capacity be equal
