DANES — Distributed algorithm for node energy-management for self-organizing wireless sensor networks

The energy management in Wireless Sensor Networks (WSNs), have been primarily attempted at the M A C layer considering communication pattern and protocols. The work in this paper proposes a node-level application layer based self-organizing energy management algorithm. This distributed algorithm performs the node-level tasks with an objective to conserve and predict node and network lifetime with a strategy that assures node reach ability in the deployed network, autonomously. Here, the self-organizing node-level based energy management algorithm refers to the ability of an individual node to self-check, self-direct and self-instruct; and attain energy conservation modes like sleep, awake, etc. on dropping/lowering the desired energy-level threshold. Further, the policy employed by the proposed algorithm has the ability to report the node-level energy-health to the controlling cluster-head/base-station using a communication protocol. The proposed work is realized and implemented on actual sensor nodes. The results indicate that the proposed algorithm has the potential, and demonstrate its merit.
