Deepali Virmani, Satbir Jain

TL;DR
This paper introduces a decentralized tree structure called DLMT for wireless sensor networks that minimizes energy consumption and extends network lifetime by selecting high-energy nodes as data aggregators, reducing maintenance and data loss.
Contribution
The paper proposes a novel decentralized tree construction method that optimizes energy use and prolongs network lifetime in WSNs, integrating with Diffusion routing.
Findings
Extends network lifetime by selecting high-energy nodes as parents.
Reduces frequency of tree reconstruction and data loss.
Minimizes delay during data collection.
Abstract
To meet the demands of wireless sensor networks (WSNs) where data are usually aggregated at a single source prior to transmitting to any distant user, there is a need to establish a tree structure inside any given event region. In this paper, we propose a novel technique to create one such tree, which preserves the energy and minimizes the lifetime of event sources while they are constantly transmitting for data aggregation in future WSNs. We use the term Decentralized Lifetime-Minimizing Tree (DLMT) to denote this tree. DLMT features in nodes with higher energy tend to be chosen as data aggregating parents so that the time to detect the first broken tree link can be extended and less energy is involved in tree maintenance. In addition, by constructing the tree in such a way, the protocol is also able to reduce the frequency of tree reconstruction, minimizes the amount of data loss,…
