“…Other than SDN, new scheduling, and channel allocation mechanisms have been proposed by Alam et al (2013) which ensure Quality of Service (QoS) for interactive multimedia applications over wireless campus networks (WCNs). The proposed scheduling and channel allocation policies give priority to delay sensitive real-time traffic flows and allocate channel dynamically.…”

Purpose-This study proposes an adaptive bandwidth management system which can be explicitly used by educational institutions. The primary goal of the system is to increase the bandwidth of the users who access more on educational websites. Through this proposed bandwidth management, the users of the campus networks is encouraged to utilize the internet for educational purposes. Method-The weblog from a university's pfSense proxy server was utilized and undergo Web Usage Mining (WUM) to determine the number of educational and non-educational websites accessed by the users. Certain formulas were used in the computation of the bandwidth which was dynamically assigned to the users. A prototyping technique was applied in developing adaptive bandwidth management system. The prototype was simulated and evaluated by experts in compliance with ISO/IEC 14598-6 and ISO/IEC 9126-1 standards. 18 Results-This study found that the prototype is capable of adjusting the bandwidth of the network users dynamically. The users who browsed more on educational websites or contents were assigned with higher bandwidth compared to those who are not. Further, the evaluated prototype met the software standards of ISO. Conclusion-The proposed adaptive bandwidth management can contribute to the continuous development in the area of computer networking, especially in designing and managing campus networks. It also helps the network administrators or IT managers in allocating bandwidth with minimal effort. Recommendations-Further work on refining the process in the computation and allocation of the bandwidth is recommended. Other techniques should be tested as well to lessen the delay in assigning the bandwidth of each user. Research Implications-The proposed method can also be implemented in other opensource networking software and applied to other organizations by changing the rules instead of considering educational websites.

“…However, the DCF is unable to provide the demand of the high priority multimedia traffics. That is why, the IEEE802.11e has been developed in order to satisfy Quality of Service (QoS) required multimedia applications [6]. It differentiates the various traffics into four different Access Categories (ACs).…”

The enhancement of channel access mechanism assures to provide Quality of Service (QoS) using the service differentiation mechanism over WLAN in IEEE802.11e. The service differentiation scheme is used in the Enhanced Distributed Channel Access (EDCA) MAC layer protocol and this protocol is used the random back-off window algorithm to provide QoS for the real time multimedia applications. However, the back-off window mechanism ensures QoS to satisfy multimedia traffic but it only the probabilistic QoS due to the random nature of the algorithm. As like as the randomness of the mobility models that can be reduced the network performance.In this paper, we analyze the proposed network performance based on the variation of randomness using different seed values and evaluate the network performance using various performance metrics in IEEE802.11e.
