无线自组织网络中的按需距离矢量路由协议(AODV)没有考虑到能量消耗的均衡性和网络生命期的问题.针对AODV的这一缺点,提出了一种高能量节点驱动的AODV协议(HN-AODV).此协议将高能量节点驱动的策略应用于按需路由发现过程,尽量选择能量较高的节点来承担转发任务,以此来平衡网络能耗.仿真结果显示,HN-AODV在基本不降低数据传输性能的前提下,显著提高了网络生命周期.这种高能量节点驱动的方案同样可以运用在其它类似的反应式路由协议中 |

We designed a High energy Node driven Ad hoc On-demand Distance Vector routing protocol(HN-AODV) for wireless ad hoc networks. The design objective is to prolong the network lifetime. To achieve this goal,in our protocol design, the path to reach a destination is biased towards those paths constituent of nodes with high energy for balancing energy consumption in the network. Our protocol embeds this high energy node driven feature into the on-demand path discovery process of an existing routing protocol AODV. Detailed protocol design descriptions were provided. Simu-lation results show that our protocol can greatly prolong the network lifetime as compared with AODV. Moreover, our idea can also work well with other existing on-demand routing protocols for wireless ad hoc networks |
