基于流量的Ad Hoc网络负载均衡路由协议

提出了一种基于流量的负载均衡路由协议T-LBRP(traffic-basedload balancing routing protocol).该协议根据MAC层接口队列长度计算流量负载,将网络的平均负载定义为阈值,并引入动态阈值概念.在路由发现阶段节点将自身的负载与动态阈值比较,根据结果有选择地转发RREQ分组,以阻止在重负载节点上建立路由;同时在目的节点采用延时应答的方法选择最佳的轻负载路径回复应答分组.仿真结果表明:与AODV协议相比,T-LBRP协议使端到端时延和归一化开销分别降低约25%和45%,与此同时,分组投递率上升约7%.

Traffic-Based Load Balancing Routing Protocol in Ad Hoc Network Prediction

Proposes a traffic-based load balancing routing protocol(T-LBRP),where the traffic load is computed according to the interface queue length of MAC layer,with the average network load defined as the threshold value.The idea of dynamic threshold is introduced to judge if an intermediate node is overloaded in the route discovery phase.Then,the RREQ messages are forwarded selectively according to the load status of each node so as to prevent heavily loaded nodes from routing.At the destination node,the response...
