Abstract:
In this paper, we consider a wireless coexistence scenario where multi-radio platforms are employed to simultaneously support periodic and non-periodic traffic. Considering a scenario where wireless terminals generating periodic traffic over one frequency band change their operating band to the other band after detecting long-term communication failures, we consider how to suppress mutual interference between periodic and non-periodic traffic over the shared channel. In this paper, we propose a transmission control alleviating negative impact of mutual interference by exploiting interface heterogeneity, traffic periodicity, and queue management. As a means to suspend packet transmissions, we propose two types of queue management: transmission control in application layer and medium access control layer. The proposed schemes realize high packet delivery ratio of periodic traffic by suppressing transmissions of terminals with non-periodic traffic at the timing when periodic traffic is expected to be transmitted by their hidden terminals. We also investigate the feasibility of the proposed schemes with experiments. With computer simulations and experiments, we investigate the practicality and effectiveness of the proposed schemes.
