Capacity analysis of best-effort broadcasting services with reliability constraint

In this paper, we consider best-effort broadcast service (BEBS) in wireless cellular networks, which can be used for location-based advertising or real-time multimedia broadcasting. Contrary to the conventional broadcasting service that aims to assure reliable data delivery to all users, we establish the objective of BEBS to maximize the effective capacity of wireless resource at the cost of reliability. In this context, we introduce the notion of target reliability and formulate the problem of maximizing the capacity of BEBS under a constraint of reliability. We derive the analysis model to investigate the effect of target reliability on the achievable capacity and validate the analysis model by comparing the analysis results with the simulation results. Both analysis and simulation results confirm that the BEBS significantly improves the effective capacity by relaxing the reliability constraint, compared to the conventional reliable broadcasting.
