Abstract
As video streaming services dominate the global internet traffic nowadays, several service providers are considering a shift towards peer-to-peer (P2P) architectures in order to lower their costs. However, these architectures tend to use the peers’ network resources aggressively without taking any energy-efficient measures. Ignoring battery constraints in a P2P service that is dominated by mobile users can significantly deteriorate the system’s efficiency and lead to low Quality of Experience (QoE) to all users. In this paper, we examine the effect of battery and energy consumption in the performance of P2P VoD systems and we present a novel distributed system that successfully utilizes peers’ upload bandwidth resources, while taking into account energy and battery resources. Its components that manage the overlay and the data scheduling are tested under extensive simulations that show promising results.
