Energy consumption has always been a hot research topic in wireless sensor networks, in this paper, a novel energy-saving routing protocol based on two-layers routing mechanism is proposed, in which, the first layer adopts the remaining energy centroid algorithm to form clusters and elect the cluster heads, and the second layer adopts multi-hop transmission to guarantee that the cluster heads can...
The design and analysis of routing algorithm is an important issue in Wireless Sensor Networks (WSNs). Most traditional geographical routing algorithms cannot achieve good performance in duty-cycled networks. In this paper, we propose a k-connected overlapping clustering approach with energy awareness, namely k-OCHE, for routing in WSNs. The basic idea of this approach is to select a cluster head...
