Heterogeneous Anchor Nodes Deployment in Large Scale Outdoor Application for Wireless Sensor Networks

Wireless Sensor Networks (WSNs) are getting more interest from industrialists as well as from researchers thanks to their low cost, low power and multi-functionality. However, their performance is greatly dependent on the process of sensor nodes' deployment. Thus, an efficient and deterministic deployment technique is needed to enhance the performance of the network. In this paper, a new deployment strategy, that we named HANDLS, is proposed based on hexagonal distribution. The proposed approach considers the coverage probability as well as the number of nodes. Simulation results show that the proposed approach outperforms available deployment techniques mainly in maximizing the network coverage and the nodes' connectivity, while minimizing the number of deployed nodes.
