Abstract

For handoff in wireless ATM networks, a call might be rerouted because ATM basically provides connection-oriented service. We propose an enhanced hybrid rerouting scheme (EHRS) for handoff in wireless ATM networks, which combines the concepts of multicast rerouting, anchor rerouting, path extension and dynamic rerouting methods to effectively reduce handoff call dropping ratio, new call blocking ratio, and handoff delay. An analytical model and simulation experiments obtain performance measurements. According to the results, EHRS performs better than the different schemes
