A Study of Handoff to Enhance the (QoS) for Cell Communication in GSM & CDMA  
  Authors : Amit Dixit; Sujata Sharma

 

As we know, Handoff is an important task in maintaining the continuity of call in cellular systems and its failure can result in ongoing call termination. As mobility in wireless cellular communication systems is its backbone, so as to enhance the quality of service (QoS) & to maintain the continuous service for users to providing a ubiquitous coverage. In this paper a brief description about the different handoff techniques in cellular systems (GSM, CDMA) moreover it compares all the handoff strategies on the basis of traffic, execution time, S/I ratio, RSS (Relative Signal Strength), call handling difficulty, handoff made and generation methods. Paper also finds the brief comparison between all handoff strategies which are used in mobile wireless communication.

This paper has gives the details of Handoff, and Different parameter required for enhance the Quality of Service in wireless communication. As communication has become the fundamental need for the human society, for this continuously no of user in the given cell area is increasing day by day, and a problem of handoff is occurring. Without much effecting the Quality of Service in communication how one can improve the quality of handoff this paper describe in details the previous study of handoff and latest work on the same. Paper also describe thoroughly handoff strategies and have learned, that handoff is the process where changing the channels like frequency, time slot, spreading codes or combination of them, are associated with the current connection during a call. The service of wireless communication depends on the handoff strategy.
