Energy and Coverage Efficient Static Node Deployment Model for Wireless Sensor Network

WSNs are energy constrained, and recent works are being carried out by many engineers and scientists to make the WSNs more energy efficient. Primarily, WSNs can be categorized into two types: random and deterministic. We have concentrated our research interest to design an energy efficient deterministic WSN. In this paper, a Seven Node Hexagonal Deployment (SNHD) scheme is proposed i.e. hexagonal deployment with an additional node at the centre of every hexagon. It has been proved by mathematical analysis and MATLAB simulation that our proposed model is more energy efficient and have higher lifetime compared to Tri-Hexagon-Tiling (THT), Square grid, and LEACH random node deployment. Moreover, by mathematical analysis it has also been shown that SNHD deployment scheme requires less number of nodes to cover any region compared to other methods.
