With the fast development of wireless communications, ZigBee and semiconductor devices, home automation networks have recently become very popular. Since typical consumer products deployed in home automation networks are often powered by tiny and limited batteries, one of the most challenging research issues is concerning energy reduction and the balancing of energy consumption across the network...
Wireless sensor networks (WSNs) with one static sink often suffer from energy hole problem, which means energy consumption of certain sensors near the sink or on critical path is much faster than other sensor nodes. Finally, network partition and isolated nodes are caused. To solve this problem, we propose an Energy-Efficient Strategy Enhancing Lifetime for WSNs based on MECA and PEGASIS. This algorithm...
Wireless sensor networks (WSNs) is an important application for real time monitoring and detecting the phenomenon in a coal mine, which can ensure the workers' life safety and reduce the financial loss. But the drawback of WSNs is that the nodes are easy to die. To balance the traffic load and optimize the networks' routing seems more important. Clustering is an effective approach to prolong the network...
With the aim of prolonging network lifetime, many energy efficient algorithms and data dissemination protocols have been proposed for wireless sensor networks (WSNs) recently. Since sensor nodes close to sink have to bear more traffic burden to forward data, they will quickly deplete their energy which leads to energy hole and network partition problem. Adding mobility into sensor networks brings...
