This paper presents a new analytical framework for the congestion control of Internet traffic using a queue threshold scheme. This framework includes two discrete-time analytical models for the performance evaluation of a threshold based congestion control mechanism and compares performance measurements through typical numerical results. To satisfy the low(More)
Traffic measurements from communication networks have shown that network traffic is exhibiting selfsimilar as well as long range dependence properties. In telecommunication networks, congestion events tend to persist, producing large delays and packet loss resulting in performance degradation. In order to guarantee Quality of Service to diverse Internet(More)
Contention Free Bursting (CFB) is a new Quality-ofService (QoS) scheme proposed in IEEE 802.11e standard. It reduces the contention overheads by allowing a station gains the channel to transmit multiple frames back-to-back in a burst. Existing analytical models of the CFB scheme have primarily been presented under the assumption of saturated traffic loads.(More)
In today's environmental world, no organization has time to wait for hours to receive data through various network channels. Everyone is looking forward to develop the Quality of Services (QoS) parameters during data transfer. IEEE 802. 11e standard for Quality of Service (QoS) in Wireless Local Area Networks (WLANs) can activate with the(More)
Active Queue Management (AQM) algorithms play an important role in fair bandwidth allocation. In order to guarantee Quality of Service (QoS) to diverse Internet services, it is important to employ effective buffer management schemes at Internet routers. Controlling the size of the buffer is determined by the dynamics of TCP's congestion control algorithms.(More)
Immune system is essential to human body as it protects our bodies from pathogens in an orchestrated manner. From a computational viewpoint, the immune system has much to offer by way of inspiration. Recently, there has been growing interest in the use of natural immune system as inspiration for the creation novel approaches to computational problem. This(More)
A procedure is one of the most important elements that should be emphasized when handling any incident related with the cyber world. It is easily forgotten by many organizations, IT administrator and users, especially when dealing with the worms attack. Using the incident response methodology as the basis to build up the STAKCERT framework, the researchers(More)
