【摘要】 利用基于LEACH的能量控制路由协议中的分簇和分布式分层结构,结合水环境无线监测网中定时数据采集、数据量稀疏特点,提出一种水环境无线监测网中的能量控制路由算法。目的是克服前者存在簇首能量消耗过快、网络能量利用率低、系统生存周期短等不足。该算法采用逐次选择的方式选择簇首,取消频繁分簇机制,提高了系统的生存周期。仿真实验结果表明,算法在网络能耗及网络生存周期方面优于基于LEACH的能量控制路由协议。更多还原

【Abstract】 Utilizing clustering and distributed hierarchical structure of an energy control routing protocol based on LEACH(ECRP-LEACH), and combined with the characteristics of water environmental monitoring data(timing sampling, data sparseness and so on), an energy control routing protocol in water environment wireless monitoring network(ECRP-WEWMN) is proposed in the paper to overcome some disadvantages of the ECRP-LEACH protocol, such as the fast energy consumption of cluster head, the low utilization rate of network energy and the short network lifetime. The algorithm adopts successive selection method to select a cluster head, and avoids the frequent clustering mechanism to improve the network lifetime. The experimental results show that the algorithm is more available than the ECRP-LEACH protocol in terms of network energy consumption and lifetime.更多还原
