Abstract: In this paper, we demonstrate the improvement in end-to-end throughput by coordinated reconfiguration of the route using the information exchanged between the routers. A coordination strategy of route reconfiguration is developed by integrating communication quality, particle swarm optimisation (PSO), and mobility control of multiple routers in the presence of path loss, noise, multipath Rayleigh fading, and interference. The route with the highest throughput is determined using communication quality oriented routing metric prior to the route reconfiguration. We then show that how a coordinator can identify the router with critical link and coordinate the actions of multiple routers to gradually steer them towards a reconfigured route with higher end-to-end throughput. The simulation results illustrate that the proposed strategy provide routes with better performance in terms of throughput as compared to the routes generated by the non-coordinated route reconfiguration framework.
