摘要
针对移动Adhoc网络中节点的有限能量供给问题,通过建立数学模型并结合路由协议的实际特点,提出了一种基于搜索具有最大可持续能量路由的节能策略,并在理论上进行了正确性证明。该策略首先将路由上所有节点可用能量的最小值即路由的可持续能量作为路由的权值,然后选择具有最大权值的路由,定量地解决了能量问题。最后以不具备能量特征的按需式路由协议AODV为例,提出了具体的节能措施,为解决类似问题开辟了一条新的途径。
Energy Problem is very important for routing protocols in moblie ad hoc networks since these mobile nodes must rely on their limited battery supply. This paper make mathematical model of moblie ad hoc networks, present a energy-aware routing strategy, which considers minimum of the remaining battery level in nodes on a route as routing cost metric and choose the route that have maximal cost metric in order to increase the operational lifetime of the whole network, improve AODV routing protocol and formulate measures in detail finally.
