A Coalition-Formation Game Model for Energy-Efficient Routing in Mobile Ad-hoc Network
Abstract: Due to their mobile nature with changing topologies and limited battery energy budgets, mobile ad hoc networks (MANETs) face serious energy issues. To enhance energy-efficient routing in MANETs this study proposes a coalition-formation game model. The nodes create coalitions according to utility functions that consider link stability, cost of transmission and energy left. Nodes can collaborate to extend network lifespan, optimise route decisions, and evenly balance power consumption, etc. The suggested model involves the application of gametheoretic notions to ensure stable coalition structure formation and promote node cooperation. Simulation studies also show the coalition-based strategy outruns the conventional routing protocols by reducing energy consumption, packet delivery ratio, and extending network lifetime. The method gives a dynamic and versatile approach to connection maintenance in MANET conditions.
