Video Communications Via Multihop Ad-Hoc Networks: Design and Implementation



Hamid Gharavi, K Ban


This paper presents the design and implementation of a mobile ad-hoc network for video communications. The network architecture is based on cluster-to-cluster operation using IEEE 802.11b FHSS (Frequency Hopping Spread Spectrum). FHSS is considered to provide a better network scalability in terms of area coverage. In this architecture, the participating nodes in one cluster communicate with nodes in other clusters via their respective mobile Access-Points (APs). The link between the mobile APs is accomplished using the Ad-hoc On-demand Distance Vector (AODV) routing protocol. Video streaming is based on H.263+/RTP/UDP/IP/802.11.b. This network has been implemented using a set of APs and PDAs devices for demonstration and field testing. In our implementation so far, the experimental set up consists of 4-clusters operating in an ad-hoc manner. The paper will present the design aspects of the proposed network as well as the overall system evaluation in terms of video quality, packet-loss rate, and number of hops.
