一种节点低能量避免的AODV改进协议

An improved protocol of nodes low energy avoiding based on AODV

文章针对ad hoc网络能量受限的特点,在分析经典AODV路由协议的基础上,提出了一种节点低能量避免路由协议——LAAODV。该协议根据节点剩余电池能量自适应地选择路由,避免低能量节点过度参与数据转发,利用NS2仿真工具对LAAODV和AODV的能耗性能进行了对比。仿真结果表明,LAAODV在节点平均移动速度、节点数目及节点停留时间3个不同场景参数下的网络能耗均有一定降低,较好地平衡了节点的能量和负载,延长了网络寿命。

For the energy-constrained ad hoc network, a low energy avoidable routing protocol called LAAODV is proposed based on the analysis of traditional AODV routing protocol. This protocol se- lects the route adaptively according to the remaining energy of the nodes, thus avoiding the over-in- volvement of low energy nodes in data forwarding. The NS2 simulation tool is used to compare the LAAODV and AODV in energy consumption. The results show that the energy consumption of LAAODV decreases to a certain degree under three different scene parameters, i. e. node average movement speed, node number and node residence time, so that the nodes energy and load are bal- anced, and the network lifetime is postponed.
