Call admission control (CAC) is a key element in the provision of guaranteed quality of
service (QoS) in wireless networks. The design of CAC algorithms for mobile cellular …

This paper presents an enhanced random mobility model for simulation-based studies of
wireless networks. Our approach makes the movement trace of individual mobile stations …

The movement pattern of mobile users plays an important role in performance analysis of
wireless computer and communication networks. In this paper, we first give an overview and …

Call admission control (CAC) plays a significant role in providing the desired quality of
service in wireless networks. Many CAC schemes have been proposed. Analytical results for …

This paper considers optimizing the utilization of radio resources in a heterogeneous
integrated system consisting of two different networks: a wireless local area network (WLAN) …

Channel holding time is of primary importance in teletraffic analysis of PCS networks. This
quantity depends on user's mobility which can be characterized by the cell residence time …

WiFi offloading is a promising technique for addressing the mobile data explosion problem.
In this paper, we consider two types of WiFi offloading techniques: 1) opportunistic WiFi …

We analyze the performance of a wireless system consisting of a set of secondary users
opportunistically sharing bandwidth with a set of primary users over a coverage area. The …

In this paper, we propose a new call admission control scheme called dual threshold
bandwidth reservation, or DTBR scheme. The main novelty is that it builds upon a complete …

Call admission control is one of the key elements in ensuring the quality of service in mobile
wireless networks. The traditional trunk reservation policy and its numerous variants give …
