Node Deployment of Wireless Sensor Networks in Long Narrow Area

Abstract

In this paper, we study the node deployment in long narrow area of wireless sensor networks. Currently, studies on node deployment of wireless sensor networks mostly concentrated in two-dimensional flat area and three-dimensional space area which are complicated or inapplicable for long narrow area. The significant difference of node deployment between long narrow area and two-dimensional area is that the nodes in two-dimensional monitored area can be deployed anywhere, while the nodes in long narrow area can only be deployed by side with the environmental constraints. Considering the coverage, connectivity and reliability, we give out the densities and numbers of needed nodes in node deployment scheme for both 1-connected cover and k-connected cover in long narrow area covered completely by sensor networks.

The effects of disorder and interactions on the Anderson transition in doped graphene

“…checked the above fitting method by the disordered cubic lattice [39], and good agreements have been achieved with the accepted scaling theories [10]. Especially, we find that the fitting curves of extended states can be approximated by I 2 (ω, L) ∝ 1/L 2 , in according with the prediction of some other theories.…”
