基于簇的无线传感器网络实时负载的研究

Research on Real-Time Load of the Wireless Sensor Network Based on Cluster

针对传感器网络处于不同的负载环境下,动态地分析每轮需要的时隙大小,针对节点处于非连续的单跳同构网络,节点数据量变化较大,提出一种基于簇的传感器网络流量负载时隙调度算法(CTRSA)。算法采用簇结构,每轮时序周期内,簇首节点实时地采集成员节点数据量的信息,据此决定成员节点的时隙。实验分析和仿真表明其能够显著提高WSN的能量有效性,延长网络的寿命。

In view of the wireless sensor node work under different conditions,unified the network topology,dynamic analysic MAC layer each round nodes needs the time slot size.As sensor nodes working in non-continuous single-hop isomorphism network,presents a cluster-based traffic load time-slot scheduling algorithm for sensor networks for Wireless Sensor Networks（CTRSA）,which is based on cluster structure,unifies distributional and the central merit.In this algorithm,the cluster head adjusts the time-slot of nodes according to their conditions,and achieves the energy consumption balancing among nodes with a low latency.Simulation result shows that the algorithm improves the network energy usability and increases the network lifetime,reduces the data packet time delay.
