摘要:

为了使无线网络满足连通性、节能、干扰较小和容错等要求,采用对节点发送功率进行适当调整的拓扑控制技术是一种十分有效的方法。现实中的Ad Hoc网络应用场景的通信情况复杂多变,网络的优化目标也可能随之发生改变。提出一种更加贴近真实环境的容错三维拓扑控制算法—OVFSS,在拓扑容错的前提下,该算法在干扰对网络影响较大时能将干扰优化到最小,在干扰影响较小时能较好地考虑节能。

关键词: 拓扑控制, 干扰优化, 容错, 节能, 优化目标可变

Abstract:

In order to satisfy the requirements of connectivity,energy conservation,low interference and fault-tolerant preferences of wireless ad hoc network,topology control is an effective method.In the real world, the environment of ad hoc network communication is complicated,and the objective of network optimization may also change accordingly.In our research,a fault-tolerant threedimensional topology control algorithm is proposed.Its optimization objective is changeable. Under the premise of fault tolerance,it can minimize the interference when the influence by the interference is notable,but pay more attention on the energy conservation when the influence is slight.
