Abstract
En 中文
In this paper, we present a set of server selection schemes that includes all crucial components of resources available at each relevant node of the network to reach at the server selection decision and at the same time attempts to maximise the system-wide resource utilisation. First in the series, a server-centric scheme is proposed that formulates the problem as distributed constraint optimisation problem (DCOP) and solves it using Fast max-sum (FMS) algorithm. Though it does not scale well in large network scenario yet it provides an estimate of the optimal values of performance metrics achievable under a specific scenario. Next, a client-centric scheme is proposed that outperforms the existing ones but does not guaranty to attain optimal Nash Equilibrium (NE). This motivates us to design another client-centric scheme that can avoid the price of anarchy by attaining superior NE of mix strategies. (C) 2015 Elsevier Ltd. All rights reserved.
