Clustered Architecture for Adaptive Multimedia Streaming in WiMAX-Based Cellular Networks

In the recent years, there has been an in-creasing demand for high quality multimedia services over wireless networks. Triple play services (voice, data and video) require data-rates of the order of several Megabits per second (Mbps). However, the large transmission distance and the limited battery power of the hand-held wireless device serves as a major bottleneck. In this paper, a novel cluster-based double dumbbell topology is proposed for adaptive multi-media streaming in WiMAX-based multihop cellular networks. The performance of the network is evaluated for a two-hop model and compared with a traditional single-hop cellular design.
