Abstract
Technology is moving very fast with time .Mobile is very important part of our life .we can enjoy mobile communication when continuous service is achieved and it is possible by smooth and successful handoff. With increasing traffic and energy demand, it is necessary to achieve efficient network .We need to maintain high quality of service and optimize energy at high traffic and at low cost so that common people can use it. Now a day’s fuzzy logic algorithm is used at different stage of cellular system, provide stability to the system and handle imprecise data.
