Though Connection Admission Control (CAC) in wireless networks has been studied extensively, the heterogeneous structure of Next Generation Wireless Systems (NGWS) makes CAC very complex. Accessibility of the subsystems at the time of connection or handoff request, availability of resources

Next generation fixed wireless broadband networks are being increasingly deployed as mesh networks in order to provide and extend access to the internet. These networks are characterized by the use of multiple orthogonal channels and nodes with the ability to simultaneously communicate with many

Abstract — The heterogeneous structure of Next Generation Wireless Systems (NGWS) makes admission control very complex. Accessibility of the subsystems at the time of connection or handoff request, availability of resources in the subsystems, user preferences, and connection class need

traction in the cellular world as well, as witnessed by the direction in which 4G+ and 5G standardization is moving. Prior academic work in analyzing such large-scale wireless networks either uses oversimplified models for the physical layer, or ignores other important, real-world aspects of the problem

The Next generation wireless networks (NGWN) will be heterogeneous which will have different radio access technologies (RATs) operating together. The Radio Resource Management (RRM) is one of the key challenges in NGWN. The Call admission control (CAC) mechanism is one of the Radio Resource

of this proposed work to focus on the analytical modeling of next generation networks protocols, F-MIPV6 and HMIPV6 using IEEE 802.11based wireless local area networks. Our simulation model considers various factors from both link layer and network layer which influence the handoff delay. The outcome of this work

The Next Generation Wireless Networks (NGWN) are expected to offer abundant services to its users. Guaranteeing the agreed upon Quality of Service (QoS), while trying to maximize the revenue of the network operators by having more number of users in the system is a challenging problem. Call

An important issue in the widespread deployment of infrastructure based wireless local area networks (WLANs) is the network design. In this paper, we propose a new WLAN design approach that focuses on assuring sufficient data rate capacity to meet expected user demand in the coverage area, while

Users in Next Generation Wireless Networks (NGWN) will have varied Quality of Service (QoS) requirements as the network operators are expected to offer plethora of services. The main objective of the network operators is to guarantee the agreed upon QoS to the users, at the same time maximize

With the provisioning of high-speed wireless LAN (WLAN) environments, multi-media services (e.g., VoIP and video-conference) with different QoS requirements will be available in next generation WLANs. Multimedia services could be categorized into multiple traffic classes and different priorities
