- Abstract
Wireless sensor networks being energy constrained systems, one major problem is to deploy the sensor nodes in such a manner so as to ensure maximum coverage and connectivity with optimal number of nodes and furthermore elongate network lifetime with maximum energy utilization. In this paper, the above problem has been tackled for a linear array. A node deployment strategy has been devised which ensures equal energy dissipation for all the nodes through a trade-off between idle and sleep times while ensuring minimal energy dissipation for the entire network during each data gathering cycle. Furthermore the deployment scheme being developed for equidistant placement of nodes, a 100 percent coverage and connectivity has been guaranteed with radio ranges remaining within appreciable limits. An analysis considering Rayleigh Fading Link model has also been presented. Extensive simulations have been carried out with encouraging outcomes and the results that have been obtained show that the network lifetime is also enhanced when compared to previous schemes.
