“…Assuming that a mob ile user does not move randomly due to the existence of roads, offices, dead-ends, shops, etc. In [130], it is argued that, if the users mobility pattern is known even appro ximately, it is possible to use it in order to manage the bandwidth reservation efficiently. This scheme has used mobility pattern for managing the efficient ut ilization of bandwidth.…”

In recent years, we have witnessed a huge interest in the study of channel allocation and handoff strategies for cellu lar systems to ensure continuous services that guarantee QoS to mobile users. In this paper, we have a detailed d iscussion of different categories of wireless channel allocation schemes. The basic purpose of the study is to provide a comprehensive review of d ifferent categories of channel allocation algorith ms in cellu lar systems and to recommend future direct ions of research in the area. The paper g ives a survey of published papers for discussing channel allocation schemes for cellular system. The QoS is always a major concern fo r the services offered through cellular systems and it is observed that there are always trade-offs among various parameters of the QoS of these services. There are many published papers which have taken care of d ifferent QoS parameters such as call b locking probability, call dropping probability along with other performance parameters. This paper provides details of the d ifferent categories of channel allocation schemes including static channel allocation, dynamic channel allocation and hybrid channel allocation studied in literature. A lso in this paper, we explore the different channel allocation strategies, including the scenarios in which channel allocation strategies based on centralized channel control, distributed channel control, mutual exclusion algorith ms and genetic algorith ms, are used. Also, we have summarizes trade-offs between different channel allocation schemes in terms of their co mplexity and performance. In this paper, channel allocation in different context of co mple x situations such as the ones arising in offering mu ltimed ia based services and other arising in the channel allocation for mobile base station systems and use of power management in channel allocation are exp lained. This paper also examines different handoff handling provision and prioritizat ion schemes proposed in the literature for cellu lar systems.

“…The fixed reservation strategy wastes valuable spectrum resource while the dynamic reservation strategy can offer efficient spectrum utilization by minimizing number of the required guard channels. In the present, there are many schemes about call admission control aiming at keeping the CDP and CBP low while maximizing the resource utilization to meet the system demand at the same time [1][2][3][4][5][6]. When the CDP decreases, the CBP will increase accordingly.…”

Abstract-Scarcity of the spectrum resource and mobility of users make Quality-of-Service (QoS) provision a critical issue in wireless networks. This paper presents a fuzzy call admission control scheme to meet the requirement of the QoS. It searches automatically the optimal number of the guard channels in a base station to make an effective use of resource and guarantee the QoS provision. Simulation compares the proposed fuzzy scheme with an adaptive channel reservation scheme. Simulation results show that fuzzy scheme has a better robust performance in terms of call dropping probability, call blocking probability, and channel utilization.

SUMMARYIn this paper, a distributed adaptive guard channel reservation (DAGCR) scheme is proposed to give priority to handoff calls. This scheme is built upon the concept of guard channels and it uses an adaptive algorithm to search automatically the optimal number of guard channels to be reserved at each base station. The quality-of-service (QoS) parameters used are the new and handoff call blockings. Simulation studies are performed to compare the present algorithm with the static guard channel policy. Simulation results show that this proposed algorithm guarantees the handoff call blocking probability to remain below the targeted threshold up to a substantially high offered load with a minimal blocking to new calls up to a moderate offered load and also shows significantly high channel utilization in all offered load conditions. This scheme is examined over a wide range of offered load. Thus, it seems the proposed scheme is very useful in controlling the blocking performances in wireless cellular networks.
