Wireless sensor network (WSN) is more and more important for various applications. In WSN, location information plays an important role in most applications, and location accuracy is crucial to some applications, such as temperature monitoring, target tracking and so on. The original DV-HOP is an important range free localization algorithm which achieves relatively reasonable localization accuracy...
In this paper, we propose an energy and storage efficient directed diffusion (ESEDD) scheme for wireless sensor networks, where the interest-associated nodes stores only neighbor nodes in the gradient direction to the sink, and when transmitting the data only the nodes which have the most energy will be chosen for next-hop forwarding. The simulation results have shown that the proposed scheme is more...
