Quality of Service (QoS) refers to a set of rules or techniques that help the network administrators use the available network resources optimally to manage the effects of congestion and to treat the applications according to their needs. The differentiated services architecture (DiffServ) allows providing quality of service to users. The major DiffServ premise is that individual flows with sim...

Network Congestion occurs when the aggregate demand for bandwidth exceeds the available capacity of a link and when the arrival rate to the router is greater than its departure. To solve this problem, it is necessary that the router must implement effective queuing algorithm that governs how packets are buffered while waiting to be transmitted. According to the dynamic of input packets and avai...

Vehicular traffic is the major problem which every country faces because of the increase in number of vehicles throughout the world, especially in large urban areas. In a conventional traffic light controller, the traffic lights change at fixed time. It does not provide an optimal solution. Many traffic light controllers implemented in current practice, are based on the 'time-of-the-day' scheme...

The IEEE 802.16m standard for Advanced mobile broadband wireless access provides a seamless application connectivity to other mobile and IP networks like UMTS, LTE and WLAN. In order to meet the ubiquitous service delivery for users, Wimax 16m supports integration of these diverse networks which are having great difference in terms of data transmission rate, Coverage, cost and supporting of ser...

As the increase in use of computing devices such as computers, tablets and smart phones there is a huge demand for the fast-growing internet traffic. Distributed traffic management frame work has been proposed, in which routers are deployed with intelligent data rate controllers to tackle the high traffic level. The traffic control protocol is unique as other traffic control protocols have to e...

We present a new intuitionistic fuzzy rule-based decision-making system based on intuitionistic fuzzy sets for a process scheduler of a batch operating system. Our proposed intuitionistic fuzzy scheduling algorithm, inputs the nice value and burst time of all available processes in the ready queue, intuitionistically fuzzify the input values, triggers appropriate rules of our intuitionistic fuz...

Active Queue Management (AQM) plays an important role in the Internet congestion control. It tries to enhance congestion control, and to achieve tradeoff between bottleneck utilization and delay. Random Early Detection (RED) is the most popular active queue management algorithm that has been implemented in the in Internet routers and is trying to supply low delay and low packet loss. RED al...

Mobile ad-hoc network is an infrastructure less network where every node has its own protocols and services for powerful cooperation in the network. Every node has the ability to handle the congestion in its queues during traffic overflow. This was done through drop tail policy where the node drops the incoming packets to its queues during overflow condition. Previous studies showed that early ...
