I would take questions like this to the SIP Forum discussion list.

Dear Ambreen,
since is not easy to clarify or justify here the convenience of doing one thesis about this huge topic (I understand "SIP over cellular networks: an analysis in terms of performance", isn't it?) 
  I recommend you to take a look at some studies comparing one 3GPP IMS (IP Multimedia Subsystem) platform (basically SIP based) with conventional GSM/GPRS platforms (Release 99). For example in [1]. 
Or simply some VoIP information sources: [2] [3]

My two cents ;-)

 Hi,
 
 I'm doing MS in computer science and wants to do thesis on SIP based VoIP in cellular networks. The problem area I had selected is the overhead involved in SIP based VoIP, with and without compression, number of calls, and context transfers in the case of handoffs.
 
 I wanted opinion around this topic, how useful this would be and if anyone can give me directions as how to go about it.
