TAILIEUCHUNG - The price of non-cooperation in reservation based bandwidth sharing protocols

In reservation-based bandwidth sharing protocols, the base station relies on the stations’ requests to allocate time slots to them. Like most other protocols, reservation-based protocols were designed with the assumption that all stations respect the rules of the protocols. | Journal of Science and Technology Volume 48, Issue 4, 2010 pp. 99-108 THE PRICE OF NON-COOPERATION IN RESERVATION-BASED BANDWIDTH SHARING PROTOCOLS DUNG T. TRAN, TRANG T. M. TRUONG ABSTRACT In reservation-based bandwidth sharing protocols, the base station relies on the stations’ requests to allocate time slots to them. Like most other protocols, reservation-based protocols were designed with the assumption that all stations respect the rules of the protocols. However, as mobile devices are becoming more intelligent and programmable, they can selfishly optimize their operations to obtain a larger share of common bandwidth. Here, we study reservation-based bandwidth sharing protocols considering the existence of selfish stations through game-theoretic perspectives. We show that this game admits a Nash equilibrium. Then, we prove the inefficiency of the Nash equilibrium. Game-theoretical analysis shows that local optimization in the bandwidth sharing problem with conflicted interests does not lead to any global optimization. Keywords. Nash equilibrium, Repeated game, Reservation-based. 1. INTRODUCTION With the rapid growth of personal networking, the demand for services in a mobile environment has been growing faster and more diverse. New protocols for personal communication must account for the presence of several different classes of traffic with diverse patterns and quality of service (QoS) requirements, and make sure that those applications coexist as comfortable as possible within the restrictive framework of mobile environment. The major advantage of reservation-based algorithms is that they provide a significant reduction in the number of collisions incurred during communication. Moreover, reservation-based protocols are very power efficient that is inherently collision free and avoids unnecessary idle listening, which are two major sources of energy consumption. Many reservation-based access protocols have been proposed for mobile networks, . [1 - 6].
