Multi Radio Diversity for Satellite-Terrestrial Mobile Communications

This paper presents the study of the resource allocation problem in hybrid terrestrial and satellite mobile communication networks. The number of terrestrial and satellite mobile communication standards is increasing, as well as the number of users in the market. Efficient access allocation schemes not only aid network operators with better resource utilizations but also provide the users with better service times, specifically required in emergency/high load situations. The degree of internetworking in access allocation procedures varies from tight to very loose internetworking. In this paper we present a parallel multi radio diversity (MRD) based access allocation scheme in a hybrid terrestrial-satellite network which through diversity gains, results in improved mean service time. The analysis is validated via dynamic system level simulation of a sub-urban area.
