Abstract
Many research in the literature address the problem of aggregating data in wireless sensor network (WSN) applications. Data aggregation techniques of WSN using external mobile elements (ME) are, recently, proposed. Only few of the proposed techniques consider the trust factor when selecting one network component to send the data to the base station. In this paper, we introduce a new trust scheme that assigns the task of sending the aggregated data to only the most reliable external MEs of the WSN, in order to reduce data loss. Experimental results show that the proposed scheme performs well in terms of reducing the data and energy loss while not negatively affecting the network coverage.
