摘要
在Ad Hoc网络中,由网络节点的移动性及能源受限导致的网络连通寿命和各个节点效率的易变性,表现了网络的自愈合性能,如何提高Ad Hoc自愈合性能成为关注的问题。针对Ad Hoc网络的连通寿命和各个节点效率问题,为达到延长网络连通寿命和提高了网络效率的目的,提出了一种新的Ad Hoc网络自愈合机制设计策略,采用将各个节点的能源信息、Ad Hoc网络即时路由信息和GPS信息结合起来作为输入因素的方法。通过仿真计算,仿真结果显示,新的自愈合机制是可行的,能使Ad Hoc网络的连通寿命延长了近10 s,网络效率提高了10%。
In the Ad Hoc network, the network connective lifetime caused by the constrained energy and the mob- ility of network nodes and the various efficiency of nodes represents its sail-healing properties. How to improve the self-healing properties of Ad Hoc becomes the mushrooming concern. In this paper, to prolong the connectivity lifetime of Ad Hoe network and efficiency of each node, a new Ad Hoe network self-healing mechanism design strategy is presented, which integrates the energy information of each node, routing information of Ad Hoc network and real- time information of GPS as input factors to achieve the extended network connectivity lifetime and improved network efficiency. Simulation results show that the new self-healing mechanism is feasible, it extends the connectivity lifetime of Ad Hoe Networks to nearly 10s, and the network efficiency is improved by 10%.
