Abstract
A wireless sensor network is characterized by resource constraint and limited computational capable sensor motes that are powered by battery. Ensuring optimal lifetime of a sensor network has always been a research question from the past decade with evidences of various ranges of solutions to mitigate them. However, till now such energy preservation solutions were not found to be effective. Another unique pattern observed from literatures is that majority of such techniques are cluster based which causes latency in data fusion mechanism. Therefore, this paper has discussed a tree-based data fusion technique using an extra module termed as core fusion node, which ensures energy aware and non-redundant data to be fused by the fusion node and then transmit to the base station using multiple-hops. Accompanied with cost effective computation technique, the proposed system (TBFT) is found to outperform conventional LEACH algorithm both with respect to energy and data fusion time, showing the effective outcome till date.
