Energy-Efficient Broadcast and Multicast in Wireless Ad Hoc Networks

This paper gives an introduction to the energy-efficient broadcast/multicast routing problem and makes a survey on recent existed algorithms.Firstly,an introduction is made to the broadcast/multicast routing problem.Secondly,the communication and energy models,the definition of energy-efficiency and the optimization objectives are clearly presented.Finally,comparison is made for existing representative algorithms in two aspects:minimum energy and maximum lifetime.Open research issues and research trends are also discussed.
