This paper highlights the studies performed to arrive at a novel handoff scheme in achieving uninterrupted connectivity. Every wireless communication user prefers seamless mobility and uninterrupted communication. Achieving this scenario is quite challenging both technologically and economically. Few of the reasons are geographical and man made constraints. Dynamic changes in environment and ever changing geographical landscape also pose serious difficulties to engineers involved in design of wireless systems. The following schemes have been suggested in an effort to improve QoS of wireless mobile communication scenarios.
