【摘要】 针对无线传感器网络数据汇聚传输协议存在的负载不均衡问题,提出了一种新的负载均衡汇聚传输协议.该协议利用竞争算法构建蓝牙分散网主干,采用"按需通告"和"故障检测"相结合的方法进行负载更新,较好地解决了同类算法不能适应流量变化和负载更新次数过多的问题.仿真试验结果表明,该协议具有较高的数据到达率和较平稳的数据传输速率.更多还原

【Abstract】 In order to balance the load of the existing data convergecast protocols in wireless sensor networks,this paper proposes a novel load-balancing convergecast protocol(LBCP).LBCP constructs the Bluetooth scatternet branch based on the competition algorithm,and updates the load information with the method combining the "on-demand notice mechanism" with the "fault detection mechanism",thus overcoming the incapability of the conventional algorithms in adapting traffic change and reducing load-updating frequency.Simulated results indicate that,as compared with the conventional protocols,the proposed protocol is of higher data delivery ratio and stabler data transmission rate.更多还原
