一种带宽和能量约束的QoS路由协议

摘要

For some current Quality of Service(QoS) routing protocols, after choosing the path from source node to destination node, the special QoS flow of satisfying demand will transport data packages with the path, until the path disconnection. This paper proposes a new bandwidth and energy constrained routing protocol named BERP(Bandwidth and Energy Route Protocol). BERP is based on classic AODV(Ad hoc On-demand Distant Vector) protocol. It modifies routing discovery and maintenance mechanism for the QoS routing protocols, which is based on AODV and featured by bandwidth. By this way, all the node energy consumptions in network become more balanced, and simulation result shows the life time of the network is prolonged.%现有服务质量(QoS)路由协议一旦选定源节点到目的节点的路径,满足要求的特定业务流将一直从这条路径上传送数据包,直到该路径断链.针对该问题,提出一种基于带宽和能量约束的QoS路由协议--BERP.该协议以典型的AODV协议为基础,修改了以带宽为指标的基于AODV的QoS路由协议的路由发现和维护机制.仿真结果证明,网络中节点的能量消耗比较均衡,延长了网络存活时间.
