基于标记的Ad hoc网络混合路由协议

建立健壮的、实用的、快速准确地到达目的节点的路由选择一直是Ad hoc网络研究的一个核心问题.提出了一种改进的基于GPSR的路由协议,加入时间标记减少了路由选择计算和传输延时,并把节点剩余能量作为路由选择的因素,实现了剩余能量均衡,解决了部分节点能量损耗过快导致网络性能恶化的情况.同时,提出了一种较好的处理空洞问题的机制,通过发送警告信息,对空洞节点进行标记,避免了节点多次通过同一个空洞而造成的能量消耗问题.

Based on the Marked Ad hoc Network Hybrid Routing Protocols

It is a core research issue to make the roubst, practical, fast and accurate routing selection to the destination node in Ad hoc networks. This paper presents animproved protocol based on GPSR, to solve the problem of the rapid collapse of the whole network performance by keeping the nodes＇ remaining energy balanced as a routing selection factor and adding the time marker to reduce the routing selection calculation and transmission delay. Moreover, the paper puts forward a better mechanism to solve the routing hole problem sending a warning message by the perimeter node to avoid passing the same hole several times that causes energy consumption.
