LEACH is one classical protocol in wireless sensor network, which is a clustering-based protocol with good performance. In this paper, an improved routing algorithm based on LEACH protocol will be proposed, which involves cluster head choosing, multi-hop routing and the building of its path. Simulation in MATLAB, an improved routing algorithm has higher energy utilizing rate, and it helps prolong...
As WSN is a resource-constrained network, especially the limited energy, so it must maintain smaller router information and reduce the energy consumption as much as possible. This paper briefly introduces the wireless sensor network, and analysis the problems existed in LEACH routing protocol. Put forward the improved algorithm based on LEACH cluster head multi-hops algorithm, and under considering...
One of important requirements for many Wireless sensor network applications is to prolong network lifetime. The cluster head consumes more energy than other member nodes, because it gathers data from its member nodes, processes it (e.g. data fusion), and transfers data to the sink node or to the base station that maybe located remotely. Therefore, the cluster head should be elected periodically within...
