LEACH protocol is considered the best in the WSN protocols in extending the network lifetime and reduces energy loss, but LEACH suffers from the problem of the correct distribution of the nodes correlation with CHs. In this paper, we propose an improved protocol called LEACH-Z(LEACH zones), this protocol improves the distribution of clusters by making the clusters near the base station(BS) larg...

Wireless sensor network (WSN) is composed of a large number of sensor nodes, it can real-time monitor and collect various information of monitored objects and passed to the user for analysis and use. This paper studies and designs a hierarchical WSN network management architecture and communication model, focus on the wireless sensor network topology control mechanism and based on the analysis ...

Wireless sensor networks (WSNs) consist of a large number of small, low data rate and inexpensive nodes that communicate in order to sense or control a physical phenomenon. The major difference between the WSN and the traditional wireless network is that sensors are very sensitive to energy consumption. Moreover, the performance of the sensor network applications highly depends on the lifetime ...

Power consumption is an important metric tool in the context of the wireless sensor networks (WSNs). In this paper, we described a new Energy-Degree (EDD) Clustering Algorithm for the WSNs. A node with higher residual energy and higher degree is more likely elected as a clusterhead (CH). The intercluster and intracluster communications are realized on one hop. The principal goal of our algorith...

Wireless sensor network comprises of small sensor nodes with limited resources. Clustered networks have been proposed in many researches to reduce the power consumption in sensor networks.
