基于LEACH的无线传感器网络最优簇头数

Optimal Number of Cluster Heads in Wireless Sensors Networks Based on LEACH

Ghassan Samara, Munir Al-okour

摘要:

无线传感器网络(Wireless Sensor Network,WSN)是近年来无线网络研究的热点之一。传感器被随机地放置在该区域中,每个节点感知周围环境并将收集到的数据发送到簇头(CH),簇头(CH)将获得的信息聚合并发送到基站(BS)。每个WSN节点上都包括一个不可充电的电池。无线传感器网络的传感器能量和网络寿命延长是学术界和工业界最重要的考虑因素。因此,许多路由协议被提出来解决这个问题,其中之一是LEACH,早期的协议,引入了分簇的思想,以延长生命的无线传感器网络。由于LEACH是随机选择的,因此会受到簇头数量的影响,这对网络寿命有影响,此外,每个簇中的节点是随机加入的,这意味着一些簇头比其他簇头工作得更多,而簇节点较少。本文提出了一种最大最优簇头数算法(MONCH)来确定无线传感器网络中的最优簇头,并找到最接近基站的簇头,以帮助将节点与最合适的簇进行整合。结果表明,改进的能量消耗性能的LEACH算法。

英文摘要:

The Wireless Sensor Network (WSN) has been one of the leading research fields of wireless networks, particularly in recent year. Sensors are randomly positioned in the region, every node senses the surroundings and sends the data collected to the cluster head (CH), which aggregates and transmits obtained information to the Base Station (BS). A non-rechargeable battery is included on each WSN node. The sensor energy and network life extension of WSN are the most important considerations in the academia and industry. And thus, many routing protocols have been proposed to solve this issue, one of these is LEACH, the early protocol that introduced the clustering idea to extend the life of the WSN. LEACH is affected by the number of heads of the Clusters as it is randomly selected, and this has an impact on network lifetime, furthermore, the nodes are randomly joined in each cluster, this means that some of the cluster heads work more than others with fewer cluster nodes. In this paper, it is proposed an algorithm Maximum Optimal Number of Cluster Heads (MONCH) to identify the optimum cluster heads in WSN and to find which is the nearest one to BS and helps to integrate nodes with the most appropriate cluster. The results show improved energy consumption performance for the LEACH algorithm.
