Abstract

In this paper, we propose multi-channel time division multiple access (MC/TDMA) scheme which provides proportional service differentiation while achieving high throughput in a multichannel wireless network. Proportional service differentiation is achieved by scheduling traffic over multiple non- overlapping channels using the modified open-shop scheduling problem analogy. This analogy allows us to use known optimal algorithms that have been previously developed for the open-shop scheduling problem. With extensive performance evaluation using OPNET simulator, we show that the proposed MC/TDMA scheme provides proportional service differentiation while achieving high throughput. To the best of our knowledge, this is the first work for provisioning proportional service differentiation in wireless networks using multiple channels.
