基于信号能量方差的链路稳定性在MANET中的应用
|
摘要
传统QoS路由协议通常基于信号强度或节点间的距离来解决链路的稳定性,导致选择最近节点时,增加了跳数,从而降低了路由的QoS,影响网络的性能。基于此,本文提出了一种新的机制,在OLSR协议的基础上,通过某个节点相对于邻居节点的移动性程度来计算链路稳定性,采用一个稳定性函数作为主路径的选取准则,有效地选择了一条关于链路稳定性的最佳路径。仿真结果表明,与OLSR ETX和OLSR相比,本文所提方法使得MPR的重复计算和路由袁的重复计算过程最小化,并减少了数据包的丢失率,降低了数据包的传输时延,大大提高了网络的性能。
The classical QoS routing protocols generally solve the stability of the link based on the signal strength or distance between nodes,which results in the increasement of the number of hops when selecting the nearest node,and thereby reducing the QoS of routing,and affecting the performance of the network.So,a new mechanism is proposed in this paper.Based on the OLSR protocol,a node calculates the link stability by the the mobility degree of a node relative to its neighbor,and uses a stability function as the main path selection criterion,so a node can choose the best path on the link stability effectively.The simulation results show that,compared with OLSRETX and OLSR,the proposed method minimizes the recalculation of MPR and the routing table recalculation process,reduces the packet loss rate and the transmission delay of the packet,and significantly improves the performance of the network.
