| Research Abstract |
In the first year, we firstly carried out performance evaluation by simulations and software implementations on notebook Linux PC about the multipath routing protocol for multi-hop wireless networks. Then, we built actual multi-hop wireless network testbed using multiple notebook PCs, and executed video delivery experiments in campus. Details are:
(1)Simulation evaluations of the multipath routing method, that switches delivery routes adaptively according to wireless channel characteristics,
(2)Simulation evaluations of the multipath routing method, that justifies wireless channel characteristics by using receiving powers of delivery routes,
(3)Implementation and modification of KernelAODV, that is an open source multihop routing protocol operating on Linux, and
(4)Implementation experiments of video content delivery over multi-hop wireless network built by multiple notebook PCs.
In the second year, we published a paper, made some presentations at domestic conferences and continued evaluations about the multipath routing protocol for multi-hop wireless networks. Details are
(1)Publication of a paper on the proposed multipath routing method and its application to multimedia content delivery,
(2)Implementation evaluations of multi-hop video content delivery using H.264/AVC instead of H.263+,
(3)Simulation evaluations of the multi-hop wireless network, that emulates actual implementation environment, and
(4)Primitive prototype implementations of a visual sensing system, as an application of the proposed multipath routing protocol and video content delivery techniques.
