Sensor Networks

Energy and sink mobility

Sensor networks are dense wireless networks where information is gathered by sensor elements spread out in an interest area. Wireless sensors applications cover a large field such as surveillance and security, target tracking, agriculture, health and military purposes. Their main deficiency is their finite source of energy. Therefore, an efficient utilization of this energy resource conditions the network lifetime. In order to enhance the performance of these networks, we focused on the mobility of sink nodes. We proposed a new dynamic approach to extend the lifetime of a sensor network based on both mobility and multiplicity of sinks. According to the evolution of the network, in terms of energy dissipation and distribution, this approach aims to find the optimal position for all the sinks in order to optimize the lifetime of the network and thus move these sinks in an intelligent manner.
