“…DCAS requires exchanging periodically and not during each call, rather it requires that periodically. Measurement-based Pre-assignment (MPr) technique [10], which employs a dynamic allocation of bandwidth to prevent handoff failure, allows the handoff calls to share a pre-reserved channel before the new calls compete for the shared channels. An adaptive QoS management scheme used to meet dynamic differences in network resources due to the mobility of mobile hosts and location-dependant errors.…”

Mobility metrics of wireless networks such as link availability, number of neighboring nodes, link duration, link state, and link stability make it difficult to provide a node with quality of services guarantee. In previous research on Quality of Service (QoS) for cellular networks especially for handling handoff connections, the design was based on a flat 2D hexagon cells. However, in reality Base Station antenna coverage is in a 3D space and there exists a blind spot; the area which is just above and bellow the radiated antenna. In this paper we introduce the concept of Blind Spot (BS) in which there is no signals to initiate a call or accepting a handoff one. In BS, the signal power equal zero. Even if there is enough bandwidth to initiate or accept a handoff call, it will be blocked or dropped respectively. We present an implementation of Static Borrowing Scheme (SBS) and we extend the dynamic-rate based borrowing scheme [1] into 3-Dimentional structure and call it 3-Dimensional Dynamic Based Borrowing Scheme (3D DBBS). The proposed new technique for resource sharing is to ensure the continuity for both originating and handoff connections in 3-D cellular networks based on Dynamic-Based Borrowing Scheme (3D BBS). This technique aims to minimize the blocking probability of the originating calls by minimizing the dropping probability of the handoff requests and maximizing the channel utilization. The results revealed that 3D DBBS outperformed the static based schemes by 5% on average even when the blind spot of the base station antenna is taken into consideration. When moving to a 3D space, the results of the simulation showed the 3D DBBS outperformed the static scheme by 2% on average. As a result, considering nodes in a 3D space will have better QoS guarantee as the blocking and dropping probabilities are decreased. Thus, the bandwidth utilization is increased.

Abstmet-This paper addresses the issue of call admission control with the necesary QaS guarantee for a micddala integrated wireless cellular network. Specifically, we propose a new call admission control policy called Dual-Threshold Call Admission Conml (DT-CAC) policy. It uses hw rhresholdr, one to reserve channels for narrow-band voice handoffcalls, and the other for wideband data handoff Irffic. Its unique features am: 1) it adopts the Complete Sharing (CS) approach that maximizes the channel emciency; 2) it derives the o p I h " se1 of thresholds that satisfies the QoS target on handoff dropping probabilities for both voice and data traffic, while at the same time minimizing the maximal new call hlwkining probability (voice or data). IQ performance is well supported by simulation results. I. INTRODUCTlONThere has been a rapid development in wireless cellular communications. The next generation of networks are expected to eventually carry multimedia traffic. One of the key issues is to ensure that the QoS requirement of the different applications are guaranteed. This paper addresses the call admission control for a voiddata integrated wireless cellular network. One of the key design goals is to limit the handoff dropping probability below a certain constraint. While cell sizes are systematically decreased to enable better frequency reuse, this also considerably increases the number of handoffs during a mobile's life time. Therefore, it becomes increasingly critical in micro or pico-cell wireless networks to have mechanisms that meet the following two challenges. First, they must maintain the handoff dropping probability at pre-specified target QoS levels. Second, in view of the increasing popularity of data services from simple short messages to GPRS, the networks must satisfy the different QoS requirements of all types of traffic.The Guard Channel (GC) based policies have been extensively studied in the traditional voice-centric cellular networks [4], (91. Its extension, the Fractional Guarded Channel (FCC) policy, is optimal for minimizing the call blocking probability subject to a hard constraint on the call dropping probability 181. For networks accommodating both narrow-band and narrow-band calls can request handoffs. Haung et al considered a voiceldata integrated system with finite buffers [SI, but the boundary for channel separation is "movable" according to traffic condition.To the best of our knowledge, there have been little studies addressing the QoS guarantee for multiple traffic types, which is the objective in this paper. Specifically, we propose a new call admission control policy called Dual-Threshold Call Admission Control (DT-CAC) policy, whose objective is to minimize the maximal new call blocking probability (voice or data) while satisfying the hard constraints on handoff dropping probabilities for both voice and data traffic.In order to maximize channel utilization, we adopt the CS approach, rather than the CP approach (21, [7]. The CP approach divides the available channels into separate...

“…However as shown in [4,14], dynamic schemes can always achieve better performance; 2) the handoff rates for both voice and data following convention have been assumed given, as there lacks adequate model that can derive handoff rates based on other parameters such as new call arrival rates and mobility, similar to those in [10]. We are currently working on the dynamic control policy based on the DP scheme, and the online parameters estimation algorithm proposed in [15] seems to be a viable technique.…”

-One of the key challenges in the design of bandwidth allocation policies for a multi-services mobile cellular network is to guarantee the potentially different Quality of Service (QoS) requirement from diverse applications, while at the same to ensure that the scarce bandwidth be utilized efficiently. Complete Sharing (CS) and Dynamic Partition (DP) schemes have been shown as viable techniques for managing the bandwidth. However, there has been no study that compares their respective performance, which is the focus of this paper. Specifically, in this paper, through both analysis and simulation, we demonstrate that both schemes can achieve comparable performance by proper manipulation of control parameters. The tradeoff is that DP scheme can more easily achieve the target QoS requirement, at the expense of over-provisioning, thus can potentially lead to less channel efficiency when comparing to a CS based scheme.
