| 摘 要： | 移动无线传感器网络(MWSN)体系结构在解决传统的网络能量消耗不均衡的问题上有显著效果,但移动sink节点的加入会增大网络的传输延迟。通过分析无线传感网络数据采集机制的耗能情况,提出一种联合动态和静态sink节点的数据收集策略HMS,在节能的同时改善网络的延迟问题,并且结合最短路径最大传输量算法优化MWSN在一个圆形监测区域的数据采集情况。系统仿真证明HMS算法在提高网络能源利用效率上的有效性。

| Abstract: | In mobile wireless sensor network(MWSN),using mobile sink as a solution for collecting the data has been shown to be an effective way of improving sensor network performances.But a mobile sink will result in a large transmission delay.The data gathering approaches to distribute energy consumption in WSN are analyzed and a scheme of hybrid mobile sink(HMS) jointing a static sink is proposed to improve the delay problem.Subsequently,combining a data collection scheme called shortest path and maximum amount to optimize the gathering scheme between members and sub-sinks in a circle sense area.Finally,the system simulation confirms that the scheme is effective on improving the energy utilization efficiency. |
