| 摘 要： | 无线传感器由于节点能量有限,sink节点作为多对一数据收集模式的中心,本质上存在能量消耗的不均衡.依据典型的传感器网络参数,主要从理论上分析了一般k跳网络的节点能量消耗特征,证明在一般k跳网络中,必定有一个最佳的k使得网络寿命最长.在此基础上,提出了一种一般k跳网络的TDMA调度算法,并给出了一般k跳网络所需时隙的上界.以此为基础,给出了一般k跳网络全网调度的策略.理论分析与数值模拟计算结果证实了算法的正确性与有效性.

| Abstract: | Sensor nodes in wireless sensor networks are constrained by battery power.And the sensor nodes sense a specific phenomenon in the environment and route the sensed data to a relatively small number of central data processing nodes,called sinks.So there exists imbalance in energy consumption in essence.In this paper,the authors are not only interested in determining a TDMA schedule that minimizes the total time required to complete the convergecast,but also consider a TDMA scheduling algorithm can which balan... |
