Connection routing schemes for wireless ATM
Upkar Varshney · 2003
Wireless ATM presents several interesting challenges, such as managing an end-to-end ATM connection (using connection re-routing) and location management, handling the high-error-rate performance of wireless links, maintaining the ATM cell sequence and supporting quality of service (QoS) requirements. Recently, the design of re-routing schemes has received some consideration in the literature. However, most of these schemes do not address support for multi-connection and the multicast handoffs that may be necessary for mobile multimedia computing. We discuss several re-routing schemes for wireless ATM networks and many issues, including multi-connection and multicast connection handoffs, and propose generic techniques that can be incorporated in re-routing schemes to support such handoffs. We also discuss how these can be incorporated in re-routing schemes such as RAC (rearranged ATM connection) and EAC (extended ATM connection).
