Modeling of burst switching for wireless packet data

Abstract

That third generation mobile communication needs to provide multimedia service with increased data rates. The efficient allocation of radio and network resources is important. This paper develops ‘burst switching’ as an efficient radio resource allocation scheme. Burst switching is known to be more efficient than circuit or packet switching. In burst switching, radio resource is allocated to a user for the duration of data bursts rather than an entire session or a single packet as in the case of circuit and packet switching. If a packet doesn’t arrive for timer value2 $(τ_2)$, physical layer is released. Also if a packet doesn’t arrive for timer value1 $(τ_1)$, upper layer is released. So two timer values to minimize the sum of access delay and queuing delay need to be considered. This paper models each switching scheme and decides $τ_2$ with the assumption that traffic arrival follows poison process. However, The simulation is preformed with Pareto distribution. The timer value2 is also decided based on the modeling and the simulation.
