| 摘 要： | 为了延长多播中共享树的工作时间,要求尽量减少节点的能量消耗。利用基于共享树的能量优化的分布式多播路由算法D-REMiT,能够降低共享树的总能耗和延长共享树的使用寿命。模拟结果显示,D-REMiT算法付出很少的共享树总能耗代价,大大提高了共享树的生存时间,有较好的收敛性,比已有的算法G-REMiT更适用于自组网环境。

| Abstract: | To extend shared tree lifetime,a distributed algorithm D-REMiT was proposed for building an energy-efficient shared tree in ad hoc networks.In D-REMiT algorithm,both the total energy consumption(TEC) and System Lifetime(SL) were taken into account while building the shared tree.The simulation results show that the D-REMiT improves SL of shared tree efficiently with little sacrifice on TEC and has good convergence,and it has better performances than G-REMiT in ad hoc networks. |
