| 摘 要： | 网络生存期是衡量水声传感器网络的一个主要性能指标.采用多跳传输机制的水声传感器网络中,靠近基站的节点最先耗尽能量,导致网络生存期缩短,针对这一问题,提出了一种网络生存期延长策略.该策略将圆形的网络区域划分成n个环,使最内环每个节点负载最小,给出了最优传输距离,为了平衡负载,采用直跳和多跳混合传输的机制,优化网络生存期.仿真结果表明,网络生存期提高显著.

| Abstract: | Network lifetime is the measure of major performance guidelines for Under-Water Acoustic Sensor Networks(UW-ASN),because the nodes near the sink consume energy so quickly that would shorten network lifetime in multi-hop transmission scheme.A network lifetime prolonging strategy was proposed to solve this problem.This strategy divides the disk area into n rings,to make the traffic load of the inner rings minimum.It offers the optimum transmission distance,in order to balancing the traffic load,then combines ... |
