An Energy-Aware Multipath Routing Algorithm for Ad hoc Networks
-
摘要: 该文针对无线移动Ad hoc网络的动态变化拓扑逻辑，存在单向链路，节点能量有限等特点，提出了一种具有能量感知的多路径路由算法。该算法是一种反应式的基于路径池的多路径路由算法，数据和应答消息的路由根据路由池中路径的性能尺度，即跳数、可靠性和剩余能量以一定的概率分布随机选择。路径的可靠性和剩余能量在数据传输过程中动态更新。仿真结果表明该算法能有效地延长网络的生存时间。Abstract: In mobile Ad hoc networks, the topology is dynamic, the energy of node is always limited, and there are always asymmetric links between nodes. This paper presents an Energy-Aware Multipath Routing Algorithm(EAMRA) which intends to prolong the TTL(Time-To-Live) of this kind of mobile Ad hoc networks. EAMRA is a connection-oriented and reactive path-pool-based routing algorithm which chooses randomly the routing for user data according to path metrics. The path metrics, reliability and residual-energy, are updated in communication process. The simulation results show that EAMRA can effectively prolong the TTL of mobile Ad hoc networks.
