In Wireless Sensor Network (WSN), one of the primary issues is energy conservation for extending network lifetime. Communication protocols for WSN help reduce the energy consumption via adopting sleep scheduling in the network. Random sleep scheduling is a desirable mechanism for its simplicity and steady duty cycle. However, the low duty cycle sleeping of nodes may destroy the connectivity of network,...
In WSNs' application, the reduction of energy consumption and the entire network's lifetime should be optimized and feasible communications are must be ensured. All of the above have become to be an important factor to evaluate the performance of routing protocols. In the paper, we present a feasible routing protocol for WSNs in coal mine. Here, we call it LEACH-mine. In the algorithm, the cluster...
The applications of wireless sensor networks are seriously constrained by energy supply. So how to prolong the network lifetime is an important and challenging issue, which is the focus of designing the WSNs routing protocol. We propose an approach of the wireless sensor network routing protocol based on ant colony optimization. The ACO approach consider not only the path delay but also the node energy...
