This demonstration focuses on seamless video delivery over Wireless Mesh Networks with Dynamic Stream Merging (DSM) capability. The overall setup consists of a prototype with seven nodes forming the mesh network backbone. All these nodes run DSM software with mobility support. DSM is a robust technique that can reduce both gateway load and wireless traffic for video applications. It has the intelligence...
In recent years, there has been a dramatic increase in the number of users who access online videos from wireless access networks. It is highly desirable that such wireless networks be robust in handling sudden spurts in demand for certain videos due to occurrences like special events. An abrupt increase in network usage should not significantly impact normal access to other regular videos or other...
We propose a Dynamic Stream Merging (DSM) technique for efficient video-on-demand services to mobile users on wireless mesh networks at the edges. DSM is a new communication paradigm, in which multicast topologies are created incrementally through dynamic merging of server streams at the mesh nodes. This is accomplished without the knowledge of the server. The formation of the multicast group in this...
In this work, we propose using video caching in the wireless relay networks (WRNs) for video on demand (VoD) service. We assume the relay station (RS) of the WRNs is capable of caching a small portion of the ongoing video stream. The cached video data can be used to accommodate new user requests. Previous works on video caching for VoD are in the context of overlay network, where the physical topology...
Moving monitoring query on moving objects is an important type of query in location based services. Existing solutions suffer from high communication cost. In this paper, we propose a distributed solution to this problem. Our approach employs two ways of communications, on-demand access and broadcast channel, to reduce communication cost. Two different indexes are proposed and evaluated using simulations...
