An Adaptive Bandwidth Request Mechanism for QoS Enhancement in WiMax Real Time Communication

Tags:
quality of service

Overview The IEEE 802.16 standard for broadband wireless metropolitan area network supports real time and non-real time services. It has a provision to design new packet-scheduling algorithms according to requirements to support Quality of Service (QoS) for real-time services. Till now published literature on WiMax states that, a Service Station (SS) requests for bandwidth to a Base Station (BS) for already arrived packets at SS from users. The BS then allocates the bandwidth to SS according to priority-based request. This paper proposes a novel adaptive-bandwidth scheduling algorithm at SS, for real-time Polling Services (rtPS), wherein the SS predicts the arrival of rtPS packets prior to the arrival and requests the BS for bandwidth in advance.

Managing convergence - the key points every company should know about

It is possible to avoid some of these problems by using strict policy management and most current routers come with quality of service (QoS) features that allow businesses to prioritise voice and video packets.

SCO denial-of-service attack intensifies

By Thursday morning, the attack had been reduced to some 3,000 packets per second and the company's servers were responding to one in every three requests. As many as 50,000 packets per second hit the company's servers on Wednesday night.

Peter Cochrane's Uncommon Sense: Hype and Skype

So the arrival times of packets can be widely distributed and vary on a second-to-second basis. For telcos, many see the arrival of the internet and Voice over IP (VoIP) as a parallel situation. On the other hand, when you send an email message via...

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?
