A fuzzy multicast method providing linguistic guarantee of disruption free service in mobile wireless networks

The goal of seamless communication is to provide disruption free service to a mobile user. A disruption in mobile service could occur due to active handoffs. There are not many user applications that require either total guarantee for disruption free service or tolerance for very frequent disruptions. In this paper, a fuzzy multicast method that provides a linguistic guarantee for disruption free service is proposed. The performance of our scheme is evaluated through a simulation with various mobile directions and mobile velocities, and we know that the fuzzy multicast method significantly reduces the static network bandwidth usage and also provides linguistic guarantee for disruption fee service.
