INTRODUCTION
With increasing emergence of cellular computing and internet, cellular wireless technologies have found its way into the limelight to supplement the increasing demand for wireless data services. Existing data services pose a challenge for the delivery of quick easy and cheap connections. The current wireless technologies are based on circuit switched radio transmission. This transmission process allocates a channel to a single user in a network for an entire communication period and when the traffic levels reach a certain threshold inefficient resource utilization is likely to be observed. Therefore the transmission method is ineffective and in order to satisfy the user demands, better methods ...
