Optimisation of dynamic interface selection mechanisms on multi-radio devices in ad hoc networks

Selecting the most appropriate output interface on multi-radio-equipped terminals leads to an optimised system. The results from both experimental and simulated analyses of two different strategies on dynamic selection of the outbound interface on multi-radio devices in wireless ad hoc networks are presented and compared. Findings from the studies are twofold. First, they show that intelligent selection of a communication interface in heterogeneous ad hoc networks leads to enhanced performance in terms of throughput and packet loss. Secondly, different strategies result in optimisation of different parameters. This latter aspect is particularly interesting since a cognitive user-centric use of the different strategies could be leveraged in order to best serve the specific service and user originated requirements.
