EAM: Energy Aware Mobility over wireless sensor networks
Amine Boubekri, Wessam Ajib, Mounir Boukadoum · 2017
Mobility over wireless sensor networks (WSNs) has been largely studied, with many protocol enhancements investigated to support mobile nodes and dynamic topological changes in primarily static architectures. Many research efforts have also been devoted to optimize energy consumption in WSN by developing energy aware protocols and algorithms. On the other hand, there have been fewer studies devoted to managing mobility and energy consumption at the same time, with the aim to balance the node energy consumption for minimum disconnects and handoffs due to energy depletion problems. In this paper, we propose a mobility framework to do so, named Energy Aware Mobility (EAM) over WSN. It uses both the link strengths between a mobile node and potential static parent nodes, and the residual energy of the parent nodes to make handoff decisions, with the side benefit of balancing the node energy distribution across the WSN. We show through simulations the efficiency of the proposed framework in comparison with ignoring the node energy states or using a standard low power routing approach.
