In wireless sensor networks, it is an important task to periodically collect data from an area of interest for time-sensitive applications. The sensed data must be gathered and transmitted to a base station for further processing to meet the end-user queries. Since the network consists of low-cost nodes with limited battery power, it is a challenging task to design an efficient routing scheme that...
In order to prolong the network lifetime, energy-aware protocols should be designed to adapt the characteristic of wireless sensor networks. Clustering is a kind of key routing technique used to reduce energy consumption. In this paper, a new clustering algorithm MNLC (Maximum Network Lifetime Clustering Algorithm) for energy heterogeneous sensor networks is proposed. The algorithm uses distributed,...
Energy balance is an important design consideration in wireless sensor networks (WSNs). In this paper, based on GPSR (greedy perimeter stateless routing), a novel location-based routing algorithm for energy balance in wireless sensor networks is proposed to improve the energy efficiency of the routing approach with respect to both of energy level and location information. Simulations show that the...
