To enhance traffic safety with efficient transportation, a vehicle public safety system is designed and implemented for collision avoidance and emergency warning. The proposed architecture for the system combines On Board Unit development with publicly available inter-vehicle wireless communication systems and also positioning devices. A communication routing scheme is proposed based on multi-hop...
Increasing demand for ubiquitous high speed data access has resulted in widespread deployment of heterogeneous wireless networking domains. Integration of heterogeneous networks presents some considerable challenges which include the demand for seamless handoff, continuity of data traffic & multimedia sessions and central authentication system, billing & security. In this paper the...
Metro Ethernet networks are rapidly becoming the networks of choice for aggregation of user traffic toward the core. It allows a wide variety of services to be carried over its infrastructure as Voice over IP (VoIP), Video conferencing, Live video broadcast, Video on Demand (VoD), and Interactive gaming. These services need large bandwidth and low delay and rely on multicasting for efficient delivery...
Ethernet has grown from its roots in LANs to cover large scale networks. A set of projects plan to enhance the features of Ethernet to be with carrier grade features like high availability, fault management, and resiliency found in other circuit switched technologies. Ethernet has been architected and designed for a shared medium, it inherently handles broadcast and multicast traffic by flooding of...
