Performance analysis of mobility-supported wireless network system

摘要

In this paper, we analyze average delay times and elapsed times of traffics generated from mobile hosts in a mobility-supported system or a wireless network system, in where traffic class is divided into three types of new connection traffic, handoff traffic, and information data traffic. In this paper, we suggest a queueing model for the mobility-supported system, in where the AP, the router, and the agent are modeled as M/G/1 with three types of priority queues allocated individually for three types of traffic. Based on the suggested model, we propose the elapsed time of data traffic in terms of the number of cells, the number of routers, arrival rates of three types of traffic and the service rates of AP/routers/agents. To analyze influences on the elapsed time with respect to arrival rate of three types of traffic and service rate of devices, some examples are given.
