In a cellular network, handoff is a process of transferring a Mobile Station (MS) from one Base Station (BS) or channel to another as the user is on the move. The handover process must take care of several parameters e.g. the handover scheme that is being used; number of free channels etc. The main objective of any handover scheme is to keep QoS up to the standard. If handover scheme fails, it leads to disruption or termination of an ongoing call which is not desirable. The quality of any network is defined by its Quality Of Service (QOS) parameters and handoff scheme plays an important role in maintaining the standards of QOS.
