In this research, three schemes are proposed to address the issues of forwarder node selection, void holes, and energy optimization. Through the use of selection parameters, fallback recovery mechanism, and transmission range adjustment, the proposed schemes outperform the baseline scheme in terms of energy consumption and fraction of void nodes.
In this research work, we propose three schemes: neighbor node approaching distinct energy-efficient mates (NADEEM), fallback approach NADEEM (FA-NADEEM), and transmission adjustment NADEEM (TA-NADEEM). In NADEEM, immutable forwarder node selection is avoided with the help of three distinct selection parameters. Void hole is avoided using a fallback recovery mechanism to deliver data successfully at the destination. The transmission range is dynamically adjusted to resume greedy forwarding among the network nodes. The neighbor node is only eligible to become forwarder when it is not a void node. Additionally, linear programming-based feasible regions are computed for an optimal energy dissipation and network throughput improvement. Extensive simulations are conducted for three parameters: energy, packet delivery ratio (PDR), and fraction of void nodes. Further, an analysis is performed by varying transmission range and data rate for energy consumption and fraction of void node. The results clearly depict that our proposed schemes outperform the baseline scheme (GEDAR) in terms of energy consumption and fraction of void nodes.
