WIA-PA网络中的基于节能的AODV路由算法改进

摘要

Energy problem is very important for routing protocol in WIA-PA Networks since these nodes only rely on their limited battery supply in bad environment. The algorithmic routing before didn't consider Energy-saving Measure. Some pivotal nodes would retreat from the Networks when its energy is used up. So the route algorithm which protects lower power route is to protect those lower power nodes, and to lenghen the time of networks existing. This paper presents an energy-saving measure which considers minimum of the average remaining battery level in the nodes on a route. Performance of energy efficiency was evaluated through simulation. It is shown that the approved protocol WAODV is more efficient in consumption of WIA-PA networks resource and energy, and more flexible in obtaining an optimized path to destinations.%能源问题对于WIA-PA工业无线网络是非常重要的;因为在恶劣的环境中它们只能依靠其有限的电池供电;传统的路由算法中,选路时没有考虑节省能最的策略,它会造成一些关键节点的过度使用而过早的退出无线网络;针对WIA--PA网络的能量受限问题,提出了一种基于搜索有较大可持续能量路由的节点方法,并对AODV协议进行改进,逸免了低能量节点的使用,从而延长了网络的生存时间;该路由协议经过了理论分析和计算机仿真的验证,具有可行性和有效性,对于WIA-PA网络的节能路由协议研究以及实现具有一定的参考价值.
