Abstract
Bandwidth reservation in mobile wireless networks is a very challenging task due to the instability of radio channels, node mobility and lack of coordination between mobile nodes. Previously proposed reservation MAC protocols reserve a slot to each real-time source assuming that the source will use the reserved slot in each super-frame. Since different applications may have different bandwidth requirements, the previous assumption may result in bandwidth wasting. In this paper, we propose BRPHT protocol which reserves bandwidth to traffic sources based on their individual bandwidth requirements. Different nodes may share the same slot, thus our protocol avoids wasting bandwidth in the presence of multimedia applications with different bandwidth requirements. Simulation results illustrate the effectiveness of our protocol.
