Video Delivery Over Wireless Multi-Hop Networks

Definition:A wireless multi-hop network is a collection of wireless nodes that dynamically form a temporary network without an infrastructure.

A multi-hop network is dynamically self-organized and self-configured, with the nodes in the network automatically establishing and maintaining mesh connectivity among themselves. This feature brings many advantages to multi-hop networks such as low up-front cost, easy network maintenance, robustness, and reliable service coverage. With the increase in the bandwidth of wireless channels, and in the computing power of devices, video applications are expected to become available in wireless multi-hop networks in a near future. However, limited network resource, severe interference/ contention among neighbor traffic, dynamic changing route, lack of QoS support, direct coupling between the physical layer and the upper layers, etc. pose many challenges for supporting video communication over wireless multi-hop networks.
