摘　　要：为了提升无线传感器网络的系统容量,有效抵抗无线通信网络信道的瞬态衰落,提出一种可用于无线传感器网络的协作转发中继传输控制方法.通过网络路由与数据链路的联合控制管理实现中继节点的协作,同时引入带宽分配因子可根据网络状况灵活地动态调整中继协作专用带宽.针对信息采集网络的特点,建立网络中每个节点到网关节点的路由,在超帧中分配相应的时隙进行信道管理.从理论及实验两方面说明了该方法的有效性,并定量分析了网络中的竞争及错误概率与信噪比、发射功率的关系,搭建了具有协作转发中继能力的无线传感器网络仿真平台,验证了所提出方法的有效性.In order to improve the system capacity of wireless sensor networks and provide efficient approach to resist the wireless communication network channel transient decline,a collaborative forwarding the relay transmission control method for wireless sensor networks was proposed.Coordination between wireless nodes was achieved by joint control and management of network routing and data link relay according to network conditions.Cooperative dedicated bandwidth could be reserved introducing bandwidth allocation factor,and could be regulated dynamically.Focusing on the data acquisition service,all wireless sensor node only needed one or more routes to the coordinator,and the corresponding timeslot in the super frame was allocated by the channel management approach.The effectiveness was illustrated from both theoretical and experimental analysis,and quantitative analysis of competition in the network and the probability of error and the signal-to-noise ratio and the transmit power were presented.Building a collaborative forwarding relay wireless sensor network simulation platform verified the proposed method.
