An Energy-efficient Node Selection (ENS) mechanism has been proposed to improve the localization precision of target tracking with low computational complexity and energy consumption. The localization is based on wireless multimedia sensor network with cellular topology. The ENS mechanism utilizes the Global Node Selection algorithm in Energy-based acoustic source localization (GNSE) and the Closest...
Energy efficiency is a key problem of wireless sensor networks. Though we already have many self-organization protocols which can build energy-saving structures, the energy cost of maintenance also must be concerned. We found that organized network structure has great impact on the energy cost in the maintenance stage and the overall energy efficiency. In this paper, we classify the self-organization...
