Multicast Mesh based Mobile Ad-hoc NETworks (MANETs) provide efficient data transmission in energy restraint areas without a fixed infrastructure.In this paper, the authors present an improved version of protocol SLIMMER developed by them earlier, and name it SLIMMER-SN.Most mesh-based protocols suffer from redundancy; however, the proposed protocol controls redundancy through the concept of forwarding nodes.The proposed protocol uses remaining energy of a node to decide its energy efficiency.For measuring stability, a new metric called Stability of Node (SN) has been introduced which depends on transmission range, node density and node velocity.For data transfer, a weighted cost function selects the most energy efficient nodes / most stable nodes or a weighted combination of both.This makes the node selection criteria more dynamic.The protocol works in two steps: (1) calculating SN and (2) using SN value in the weighted cost function for selection of nodes.The study compared the proposed protocol, with other mesh-based protocols PUMA and SLIMMER, based on packet delivery ratio (PDR), throughput, end-to-end delay and average energy consumption under different simulation conditions.Results clearly demonstrate that SLIMMER-SN outperformed both PUMA and SLIMMER.
