中文摘要：
针对移动ad hoc网络终端能量资源受限对全网路由的影响,提出一种具有终端节点能量感知的路由协议（EARP,energy-aware routing protocol）。该协议能够根据单个节点能量的使用情况以及全路径的能量消耗情况选择不同的传输路径,在路径断裂时,增加本地维护策略,有效减少了由此引起的发包重传情况,提高了路由效率。通过节点能级的设定,防止链路传输过程中由于能量耗尽而导致的路由断裂情况。经过NS2仿真实验与其他相关路由协议进行比较,结果表明在相同的实验环境下,该路由协议能够有效均衡负载,保护低能量节点,延长网络生存时间。
英文摘要：
An energy-aware routing protocol（EARP） was presented to minimize the effect of limit energy supply of ter-minals in ad hoc network.In the novel protocol,different transmission paths based on service state of single node and en-ergy consumption of the whole network could be chosen.When transmission path was broken,local maintaining strategy was evoked to reduce re-transmission of data packets and therefore route efficiency was improved.Moreover,node en-ergy levels were introduced to avoid transmission link brake caused by energy exhaustion.Simulations were carried out on NS2 platform.The results show that,in the same simulation environment,comparing to other routing protocols,this routing protocol performs more effectively on balancing the traffic load,protecting low energy nodes and prolonging the network lifetime.
