Abstract: Next generation networks are heterogeneous in nature due to presence of various radio access technologies (RATs). Hence seamless mobility of users can be achieved by vertical handover (VHO). The main aim of this research paper is to design and implement an algorithm for making decision for handover in femto environment. The algorithm is designed using fuzzy logic, considering received signal strength (RSS), channel capacity, velocity of user, number of users latched, latency and jitter. The decision to perform handover between femto cell and macro cell is presented. We have considered two scenarios i.e., handover from femto cell to femto cell and handover from macro cell to femto cell.

Keywords: VHO; vertical handover; VHDA; vertical handover decision algorithm; heterogeneous wireless networks; RSS; received signal strength; channel capacity; fuzzy logic; universe of discourse.
