Feedback-based cooperative content distribution for mobile networks

A feedback-based scheme for cooperative content distribu- tion for mobile systems aimed at reducing energy and li- censed spectrum usage is presented. The paper is motivated by the problems in implementing peer-to-peer based content distribution in mobile networks due to the risks of unfair en- ergy expenditure. A technique for incentivizing cooperation and for enforcing agreements between peers is discussed as well as the dynamics of the resulting barter-like economy. Rationale for a heuristic solver is provided together with simulation-based analysis of expected savings. The scheme is evaluated for cases with deterministic as well as random initial conditions.
