“…Connection admission control (CAC) is one such solutions for the management of wireless resources to maintain better quality of service [10]- [12]. CAC algorithms are responsible for determining the admission or otherwise of a new or handoff connection as a function of network resources availability without compromising QoS requirements of existing connections [13], [14]. The most important concerns of CAC in WiMAX is ensuring QoS of different connections [15].…”

In order to provide solution to limited network resources in heterogeneous wireless networks supporting different applications with distinct quality of service (QoS) requirements, call admission control (CAC) schemes are implemented. This work is aimed at investigating three mostpopular CAC schemes employedin mobile worldwide interoperability for microwave access (WiMAX), namely dynamic CAC with bandwidth reservation (DCACBR), QoS-aware CAC (QoSACAC), and QoS guaranteed CAC (QoSGCAC) to identify their shortfalls which will form the focus of future research. A general platform is developed and simulated. The simulation was based on the following KPIs: blocking rate, dropping rate, and throughput for new and handoff connections. Simulation results for new connection shows that QoSGCAC outperforms scheme DCACBR and QoSACAC, having 26.9% and 8.56% improvements in throughput and 63.11% and 24.17% in blocking rate respectively. For handoff connection, QoSACAC showed the best performance having 13.25% and 47.84% improvements in throughput and 6.8% and 49.3% in blocking rate as compared to the DCACBR and QoSGCAC, respectively. Result analysis shows that QoSACAC has the best performance however, it admits new connections and degrade existing connections but failed to consider the delay-intolerant service classes. It is recommended that the QoSACAC be further improved.

“…This network can be categorized into two operating modes: a mandatory Pointto-Multipoint (PMP) mode and an optional mesh mode. In PMP mode (Akashdeep et al, 2014;Ali et al, 2009), all SSs are only one-hop away from the BS and communicate to the BS directly in a centralized manner and not indirectly with other neighboring SSs. In optional mesh mode (Akyildiz et al, 2005;Kas et al, 2010), all SSs are one hop or more than one hop away from the BS and so the SSs communicates with the BS directly or indirectly (i.e.…”

WiMAX is one of the broadband wireless access technologies, which provides the efficient QoS to the large number of users. The multimedia applications such as real time and non-real time services are gaining importance in the WiMAX network. To support such applications, there is a need to propose an efficient QoS traffic prediction routing protocol for the WiMAX networks. To address this, the authors are using Gene Expression Programming technique. They have generated datasets for CBR based traffic and file transfer applications. Here, they focus to develop the mathematical expressions for throughput of the network in terms of bandwidth, average end-to-end delay and average jitter for CBR based traffic and file transfer applications, so that they can analyze and predict the QoS traffic of the network. The simulation results show that the model values and the target values match with better approximation. Further, sensitivity analysis has been carried out for both CBR based traffic and file transfer applications.
