A Smart Energy-efficiency Deployment Scheme for Lifetime Enhancement in Large-scale Wireless Sensor Networks

Abstract

The exploitation of an energy-efficiency deployment scheme for green wireless sensor networks (WSNs) is a challenging issue since WSNs have become more complex and have achieved a larger scale. Meanwhile, most of the current deployment schemes cannot be transferred directly into complex networks. Therefore, this paper presents a deployment scheme to address this question and achieve green, networked WSNs. First, a hierarchical structure is proposed to deploy WSNs generally. Then, based on this structure, an energy optimization problem is constructed to realize green WSNs. Next, the question is solved by an optimal path and minimal energy consumption algorithm (OPMECA). Extensive simulations demonstrate that our energy-efficiency deployment scheme is applicable to green WSN deployment through the network lifetime and energy consumption in comparison with other algorithms.
