The multi hop architecture can provide greater range, spatial e ciency and throughput with lower power consumption than a traditional point coordinated design. In addition, the self-con guring, self-healing characteristics of this architecture enable previously infeasible network scenarios and applications. These bene ts have motivated a signi cant volume of research. Unfortunately, the ISO net...

Ad-hoc networks are an emerging technology with immense potential. Recent advances in high-tech sensors, communication devices and microprocessors has given rise to a growing commercial interest in ad-hoc networks for inter-vehicular communications. Most of the research in inter-vehicular communication systems has focused on driver safety, accident reporting and multi-hop routing. There is an e...

The IEEE 802.11 MAC standard for wireless ad hoc networks adopts Binary Exponential Back-off (BEB) mechanism to resolve bandwidth contention between stations. BEB mechanism controls the bandwidth allocation for each station by choosing a back-off value from one to CW according to the uniform random distribution, where CW is the contention window size. However, in asymmetric multi-hop networks, ...

Next generation communication networks will comprise third generation (3G) cellular and multi-hop ad hoc networks. MPEG-4 video streaming can be a killer application for this novel multihop cellular network. The paper has evaluated the end-to-end performance of streaming MPEG-4 video over a multi-hop cellular network that comprises the High-speed Downlink Packet Access (HSDPA), Universal Mobile...
