QoS in UMTS

I am working on my masters project and have simulated a network which is a an integration of cellular and ad hoc i.e. nodes have the ability to talk amongst themselves and base station. The overall delay and quality of service is very poor from the statistics. (mainly delay). I need to know if there is a QoS algorithm that I can use in my simulation to improve QoS. I am using OPNET for my simulations. I was thinking of parameters such as Delay, BER and a priority bit depending on class of traffic.

Re: QoS in UMTS

The QoS systems in Cisco´s devices are more hardware dependent than the Universities queries theory ( Erlangs ...). This is a big question that I wondering since I learn the Cisco´s Queues functions (RED ...) so if you want to properly study for QoS and queues you have to know how the Cisco´s hardware treat the traffic inside ( ASICs... ). This is my opinion after considering it for some time.

Re: QoS in UMTS

Could you let me know what are the Cisco's Products for QoS in UMTS/WLAN (as I am working on both). And where would I go to understand how the ASIC's function.

It might be a very vast question to answer but the reasoning you have given surely makes a lot of sense so I might as well ask you...what's next.thanks

Re: QoS in UMTS

Hello Mr Vikrant,

I am also doing a similar kind of simulation of "Integration of WLAN & 3G Mobile networks".

Can u provide me with some details regarding your project.

I also need to know whether this kind of simulation is possible in Matlab & Simulink modeling tools.

Regards,

Kaustubh
