Abstract

"Handoff behavior induced by user mobility is a unique phenomenon existing in wireless mobile communication networks. A connection once established may have to undergo a number of handoffs before it is hung up or dropped. A two-state Markovian queueing model is constructed in this paper to understand the performance of a VBR call in a wireless ATM network when handoffs are taken into consideration. The performance measures examined are the mean and jitter of an ATM cell. The model is extended to tri-state if call termination due to handoff failure is further incorporated in the model."
