With the constant development of multimedia technologies and mobile devices, the demand of transmitting multimedia streams to mobile devices will be one of the major applications in wireless networks. However, IEEE 802.11 does not support reliable multicast due to its inability to exchange ACKs with multiple recipients and the influence of signal interference, congestion and hidden terminal problems...
Multimedia Information delivery in public transportation systems is gaining increasing prominence. This paper proposes mesh-tree architecture for low latency and high-throughput data transfer to mobile vehicles along approach roads in and around a bus station. Prior works have demonstrated 802.11b-based wireless chain topology for mobile vehicle connectivity along railroads. However, the chain topology...
The usage of multimedia applications such as IP-TV and Video On Demand over wireless networks becomes more and more popular. In many cases the bandwidth of the wireless channel is the system bottleneck and thus it is important to increase the ability of wireless networks to provide a scalable service for multiple users simultaneously. The main idea proposed in this paper is based on a dynamic bandwidth...
