REROUTING FOR HANDOFF IN A WIRELESS ATM NETWORK

Handoff is the procedure by which a user's radio link is transferred b etween radio ports in the network without an interruption of the user connection. In this article, we discuss how a wireless asynchronous tr ansfer mode (ATM) network may reroute a user connection during a hando ff. The authors proper a novel procedure called ''Nearest Common Node Rerouting (NCNR).'' NCNR is designed to perform the rerouting of user connections due to a handoff event in a fast and efficient manner. The authors conclude by comparing NCNR to other rerouting schemes discuss ed in the literature.
