Abstract

Third generation wireless networks carry traffic from heterogeneous sources such as voice, data, video or multimedia with a specified quality of service. Efficient traffic management schemes should be developed to provide seamless access to the wireless network. In this paper, we propose a novel cell switching (e.g., packet handoff) scheme to support QoS guarantee for downlink in EGPRS (Enhanced General Packet Radio Service) network. We define the new packets and handoff packets for each type of traffic and devise a new prioritization scheme at the buffer of the base station. We present the procedure to find the optimal thresholds satisfying the QoS requirements. Using the ON-OFF approximation method for the aggregate traffic, we compute the packet loss probability and the packet waiting time. The performance of the proposed scheme is evaluated by simulations and numerical analysis In terms of packet loss probability and pocket delay.
