QoS is measured by the following factors:
• Reliability
• Delay
• Jitter
• Bandwidth
A currently used important method of improving QoS is priority queuing where each flow is assigned a priority and put into a priority class based on a given priority value. The highest priority queue is processed first and the lower ones subsequently.

An improvement that can be made to this method is the time based multiplexing where the time based allotment is dependant on features of the requests in the queue. This can be implemented at the application level for determining how much fraction of time should be set aside for servicing each type of request.

If we consider a specific application, it handles several types of requests from different gateways. However, every application has different requirements and hence a static Time Dependant Multiplexing is redundant.
In an application specific environment, usage at a particular time for a particular subservice is always influenced by the usage of all other subservices at some time before....

Biologically Inspired QoS Aware Routing Protocol to Optimize Lifetime in Sensor Networks

- I. INTRODUCTION A WSN is a self-directed set of portable or movable systems that communicate over relatively bandwidth constrained wireless links. As it is a decentralized network, all the network related activities such as, including topology realization, routing, event delivery, etc., must be incorporated into the mobile nodes. In recent years, the internet users have drastically increased, thereby the demand for real time and Quality of Service (QoS) constraints also needs to be improved [1]....   [tags: decentralized networks]

Essay on Architecture for Statistical Multiplexer

- Introduction Twenty-first century communications will be dominated by intelligent high-speed information networks. The rapid growth of high-speed networks has led to many technological as well as social developments. As the networks supporting these services shift from the experimental phase to commercial operation, the pricing of limited resources will become an important problem. In this paper, statistical Multiplexer with QOS parameter control is implemented using VLSI design technologies. In communications systems by far the most common form of multiplexing is that of time division multiplexing (TDM)....   [tags: VLSI,flow chat,QOS]

Flow Visualisation using Shadowgraphy Technique Essay

- Flow Visualisation using Shadowgraphy Technique Shadowgraphy is one of the optical techniques for observing a flow in a transparent medium. The basic apparatus consists of a light source and a recording plane onto which the shadow of the varying density field is projected. The technique is based on the variation in refractive index of the transparent media caused by density variation in the flow field. The experiment is carried out in the laboratory and density gradient is created by generating temperature gradient or any other means (diffusion of perfume)....   [tags: gas dynamics, propulsion, optical techniques]
