基于能量感知的AODV路由协议
摘要
AODV协议是基于最小跳数的
而没有考虑节点的剩余能量
这就容易使某些节点过早的死亡。针对这一问题
结合能量有效路由
提出了一种基于能量感知的AODV协议(AODV-EA)。新考虑了节点的剩余能量
在路由建立过程中
中间节点转发路由请求RREQ时
延迟一个与能量成反比的时间
这就最大可能地选择了路径中节点能量大的路径。仿真结果表明:改进的协议与原协议相比
推迟了节点的死亡时间
降低了丢包率。
Abstract
AODV protocol is based on minimum-hop
it didn’t consider the node’s remaining energy
so some nodes in the network are easy to die earlier.Aimed at this problem
considering the energy aware routing protocol
a kind of energy-aware-based AODV protocol(AODV-EA) is proposed.In the new protocol the node’s remaining energy is considered.In the course of the routing building
when the routing request is transmitted by the middle node
a time that is inverse to the node’s remaining energy must be delayed
in this way it is likely to choose a routing that is powerful.Simulation results show that compared with the old protocol
the new protocol puts off the node’s death time and reduces the packet lost ratio.
