在移动自组网中,减少移动节点电池能量消耗,延长网络总的寿命时间,已经成为路由协议性能评价的重要方面。本文提出了一种新的路由选择度量,它综合考虑了节点的剩余能量,路径的延时和跳数,试图通过一种最优路径选择算法来保护网络中的低能量节点。结合该度量方式还提出一种路由选择协议LBAODV(Load Balancing based Ad-Hoc On-Demand Distance Vector Routing),仿真结果表明,该协议能够使节点能耗与负载的分布更为均匀,相比以前相关的路由算法有效提高了吞吐量。
In mobile ad hoc networks, reducing battery energy consumption of mobile nodes and prolonging the total network lifetime has become an important aspect of the performance evaluation of routing protocols. In this paper, a new measure of routing is proposed, which considers the remaining energy of nodes, the delay of paths and the number of hops, and attempts to protect low-energy nodes in the network through an optimal path selection algorithm. Combined with this metric, a routing protocol LBAODV (Load Balancing based Ad-Hoc On-Demand Distance Vector Routing) is also proposed. Simulation results show that this protocol can make the node energy consumption and load distribution more uniform, compared with the previous correlation The routing algorithm effectively improves the throughput.
