Call admission control in mobile cellular networks: a comprehensive survey

Abstract

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 networks is especially challenging given the limited and highly variable resources, and the mobility of users encountered in such networks. This article provides a survey of admission control schemes for cellular networks and the research in this area. Our goal is to provide a broad classification and thorough discussion of existing CAC schemes. We classify these schemes based on factors such as deterministic/stochastic guarantees, distributed/local control and adaptivity to traffic conditions. In addition to this, we present some modeling and analysis basics to help in better understanding the performance and efficiency of admission control schemes in cellular networks. We describe several admission control schemes and compare them in terms of performance and complexity. Handoff prioritization is the common characteristic of these schemes. We survey different approaches proposed for achieving handoff prioritization with a focus on reservation schemes. Moreover, optimal and near-optimal reservation schemes are presented and discussed. Also, we overview other important schemes such as those designed for multi-service networks and hierarchical systems as well as complete knowledge schemes and those using pricing for CAC. Finally, the paper concludes on the state of current research and points out some of the key issues that need to be addressed in the context of CAC for future cellular networks.

Conventional and Unconventional Cellular Admission Control Mechanisms

“…A Call Admission Control (CAC) is an algorithm of decision-making that provides QoS in the network by restricting access to the network resources (Ghaderi & Boutaba, 2006). Figure 2 explains the CAC's functionally.…”

“…Figure 3 shows a taxonomic tree of the CAC techniques used, adapted from (Ghaderi & Boutaba, 2006). The difference for Ghaderi & Boutaba (2006) tree is that they does not present a single tree.…”

Efficient Algorithm for Vertical Handover in Heterogeneous Wireless Mobile Network

“…mobile cell phone, tab-pc, Laptop) to handover among the various types of networks i.e, cellular, wireless area network (WAN, wide local area network (WLAN) [1]. As we look back to the traditional cellular approach to the communication which also mention with name GSM, the predefine threshold which compare different parameters in specific order is basically used to handle handover decisions [2] the handover are not only cause of ongoing call connections but it can be helpful in order to provide best services package and to fulfill their requirements for stable communication with the comparison to horizontal handover the newly presented vertical handover not only based on the received signal gain which is known as RSS but also the different services i-e class mapping among the handoff-out and handoff-out networks [3] high data rate services (HDS) and Nonpareil global roaming (NGR) eminent fourth generation 4G from the previous of wireless networks (WN) [4], [5].the 4g networking model contains, mobile nodes or handsets terminals connects by different multiple interfaces which will be able to select the best suitable link for access among the all available alternatives. Those ace links consist of IEEE 802.11 access of wireless local area network (WAN) [6].…”
