Performance Evaluation of the Hierarchical Handoff Scheme for Wireless ATM Networks
Nadjia Kara, Jean Conan, André Girard · 2000
One of the most important issues in wireless networks is handoff. Recently, a hierarchical protocol has been proposed to manage handoff in wireless ATM networks based on the partial rerouting strategy and the virtual connection tree concept. In this paper, a discrete time model is proposed to estimate the connection bandwidth and the connection handoff delay of this scheme. We propose to compare the hierarchical protocol with the Akyol and Cox handoff protocol. Numerical results illustrate that for the future wireless ATM networks the hierarchical model gives lower connection bandwidth and lower connection handoff delay than those of Akyol and Cox model.
