Sistema cooperativo sobre redes inalámbricas globales

Abstract

Strategies for cooperation between terminals have been proposed to improve the spatial coverage, reliability and throughput of ad hoc and cellular wireless communication systems. In this paper, we consider a scenario (rather common in practice) in which a given user has access to several wireless terminals (laptop, PDA and mobile phone, for instance), all of them located in a close neighborhood. For this scenario we propose the architecture and signaling protocols of a new cooperative system, which increases the overall throughput of the user. The cooperative system consists of a Bluetooth-based local network between the source and the cooperating terminals, which is connected through a Resources Sharing Gateway with the IP network core or IP service provider.
