ABSTRACT



Mobile communication with the new technology is the quickest growing space with often accrued information rates and coverage areas. The future challenge is to form the simplest attainable use of the obtainable different types of network .For connecting mobile heterogeneous networks handover is critical. Uninterrupted quality service is the main advantage of mobile cellular systems. Handover could be a key idea to achieving quality. The event begins once user starts moving to different base station and leaves the earlier base station conjointly attainable for a user to travel from one cell to a different, with no interrupt thatís better-known as seamless association. In this paper, OPNET MODELER does the proportional analysis of soft & hard handover over metro cities operating environment like as Delhi, Mumbai, and Chennai etc. Here ten mobiles square measure playing handover within the logical space at the intervals of soft & hard limits and evaluating the performance which handover offers better which handover offers better outcome. This paper also tests how the performance of network improved with the soft handover.
