Intelligent power management (IPM) for a WSN is crucial in maximizing the operational longevity. An established regime for achieving this is through the opportunistic hibernation of redundant nodes. Redundancy, however, has various definitions within the field of WSNs and indeed multiple protocols, each operating using a different definition, coexist on the same node. In this paper, we advocate the use of an MAS as an appropriate mechanism by which different stake-holders, each desiring to hibernate a node in order to conserve power, can collaborate. The problem of node hibernation for the heterogeneous sensing coverage areas is introduced and the manner by which it can be solved using ADOPT, an algorithm for distributed constraint optimization, is described. We illustrate that the node hibernation strategy discussed here is more useful than the traditional stack-based approach and motivate our discussion using IPM as an exemplar.||Funding Details:||Science Foundation Ireland||Type of material:||Journal Article||Publisher:||Oxford University Press||Journal:||The Computer Journal||Volume:||54||Issue:||3||Start page:||490||End page:||502||Copyright (published version):||2009 The Author||Keywords:||Coverage; Connectivity; Hibernation; Intelligent power management; Distributed constraint optimization||Subject LCSH:||Wireless sensor networks--Energy consumption
