experimental study of voip quality of service implementing over cognitive radio network - open to bidding

hi, I have a project for developing simulation model for experimental study of voip quality of service implementing over cognitive radio network. I m at very last stage of my project now, n I think this is mostly similar to your previous project as you have already completed ..so I though it could b finish by a day...but with extra conditions of cognitive radio network. well talking about the requirement of my Project required codecs are :G.711, G.723.1, G.732.1, G.729... I m not sure if you are asking about the types of data but in call there should be voice and we must test the call in different environment like single calls to multiple calls ..those multiple number of calls will goes upto 10. also there mist b a case in call quality if the quality goes worst ...wht should be done...drop the call or switch to next available channel...also there is the case of primary and secondary user in cognitive radio network.....if primary user wants to use tht spectrum ...wht to do..these are the types of decision making process.... most important is to determine the qulity of service calls.. with different factors like packet loss, jitter...end to end delays etc. finally I would like to review again n if attenable please do let me know ... thank you.. hope to hear you soon. waiting for further discussion
