To balance energy consumption for nodes in wireless sensor network (WSN) is an important considering factor. A simple model is set up to analytically evaluate the energy consumption in WSN by using aggregation mechanism. It is show that energy consumption of an aggregation node increases so rapidly in the neighborhood of the sink node. A modified hierarchical data aggregation strategy is proposed...
Nowadays, wireless sensor networks appear to be mature enough to be used by business applications. These applications rely on trustworthy sensor data to control business processes. In this paper, we propose an approach to assess the trustworthiness of sensor data during their lifecycle, from acquisition at the nodes, through processing, to delivery to business applications. We rely on the subjective...
With the emerging practical application and rapid advancement of WSN in EHS, this paper addresses the particularly important problem on healthcare sensor information fusion. On light of the common ground among WSN, MAS and RST, some hybrid and multi-agent approaches are discussed and implementation details of the method are given, and as can be seen, the proposed solution MADHSDN, which results in...
