SROAM: An end-to-end service model for improved performance in roaming over wireless LAN networks

Nowadays mobile devices enable users to have various ways to surf on the Internet and broad band communication channels facilitate applications of online multimedia. Most of network real-time multimedia applications run on TCP/IP protocol stack. Although several protocols are proposed to handle the mobility management on network layer the real-time stream transmission yet suffer severe roaming interruption anti hence worsen the playback performance. This paper analyzes the roaming delay and transmission throughput in detail and evaluates the effect of multiple elements constituting the whole roaming delay. A service codenamed Swift Roaming System (SROAM) is proposed to reduce the roaming delay and increase the average transmission throughput. Some initial experiment results are provided to support the effectiveness of the methods proposed in the system.Computer Science, Hardware & ArchitectureComputer Science, Software EngineeringEngineering, Electrical & ElectronicTelecommunicationsCPCI-S(ISTP)
