Description
Summary:One of the most critical and challenging issues when developing wireless sensor networks (WSNs) is how to extend the network lifetime. Sensors are energy-constrained devices that require developing minimization techniques and mechanisms in order to exploit perfectly the energy and to prolong as long as possible the overall network lifetime. In this paper, we propose a limited energy consumption model for P2P wireless sensor networks, which takes a benefit of the Chord assets and adapts this last one so that it will be suitable for P2P WSNs. Chord in its basic form optimizes the path length by minimizing the number of hops, but it does not optimize the energy, since it was designed for wired networks. The key idea of our proposal is to optimize both the number of hops and the energy consumption to provide an energy-efficient routing scheme for P2P WSNs. The proposed enhanced Chord scheme makes a use of only Cluster-Heads ( with the strongest level of energy ) to construct the ring, which reduces the Chord topology while preserving the network connectivity. In the enhanced Chord scheme, Cluster-Heads are elected automatically and dynamically over the time, which helps to extend the network longevity. Simulation results show that the proposed scheme proves good performances in terms of hops number, alive nodes over the time and energy efficiency.
