Train accidents continuously occur due to a variety of causes (carelessness by the conductor, broken wheels, disaster during train movements, etc.). To prevent train-related accidents in advance, it is considered the monitoring train systems with wireless sensor networks (WSNs). In this paper, we propose an efficient algorithm to dynamically configure WSNs-based trains for relaying sensing data via...
This paper describes the design and implementation of MBS (multicast & broadcast service) server for mobile IPTV service in WiMAX networks. Based on interoperability requirements of WiMAX networks, the presented MBS server was implemented for mobile IPTV services and basically provides MBS service announcement and session management functions, dynamic MBS zone management, and MBS data transmission.
In this paper, a novel prefix-based patching algorithm named DP2 (Dynamic Prefix-based Patching algorithm) is proposed for mobile IPTV service in the WiBro system. Proposed algorithm increase the resource utilization of wireless bandwidth and server. It uses the prefix caching in proxy server to batch those requests that demand the same video. This algorithm just requires the mobile terminal can receive...
