Title
Impact of network parameters on the design of energy-aware cooperative content distribution protocols.
Abstract
This work presents an analytical study that investigates the impact of important network parameters on the energy consumption and group formation of a set of requesting mobile terminals that are interested in downloading cooperatively a common content. The optimal grouping of the mobile terminals, in which selected mobile terminals download the content from the base station and transmit it to other mobile terminals within their group, to minimise their total energy consumption, is an NP-hard problem. Consequently, several heuristic algorithms have been proposed in the literature, which take into account only few network parameters that became conventional in energy minimisation problems. The main contributions of this work are the following. We show that it is hard to derive the optimal energy consumption expressions in a network with a general topology where the mobile terminals can be at any location. Thus, we consider a grid network, which is a commonly used model in ad hoc and sensor networks, where it is feasible to derive the optimal energy consumption expressions as a function of the various network parameters. Results demonstrate that ignoring conventional network parameters, in the design of energy efficient content distribution protocols, deviates the solution notably from the optimal one.
