Proposed in this paper is a wireless sensor network source localization algorithm in the three-dimensional space. By using the measurements of the received signal strength (RSS), two closed-form none-ambiguous estimators are proposed to geometrically locate the source position under the shadowing noise in the wireless channel. The dynamic adjustment scheme has been applied in the localization algorithm...
This paper presents a new three-dimensional positioning algorithm, named 3DPHDV-Hop, which can significantly improve the performance in terms of positioning error and coverage by using self-tune selection of projection plane and exploiting partial average hop size instead of global average hop size in wireless sensor network. The simulation results show that the accuracy of our proposed algorithm...
Cluster-based routing protocol is currently a hot research in wireless sensor network. In this paper, we propose an improved method RECHS(Redundant and Energy-efficient Clusterhead Selection) for LEACH protocol to balance network load and to extend the network life. In order to selecting reasonable clusterheads, our scheme first selects initial clusterheads and initial redundant clusterheads. By comparing...
On the basis of analyzing, comparing the routing protocol and learning from the advanced thinking, the author proposes the algorithm of wireless sensor network routing based on gradient and the residual energy ant algorithm. Using the character that ant algorithm is simple and easy to realize, works in the part, and it integrates link quality into pheromone and supports many links to design the wireless...
