Abstract

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 many user applications that do not require total guarantee for disruption free service, and also not tolerate very frequent disruptions. This paper proposes a fuzzy multicast method that provides a linguistic guarantee for disruption free service. The linguistic guarantee for disruption free service is specified by a mobile user, then the proposed method forecasts the direction and velocity of a mobile host, and data packets for the mobile host are transmitted to a part of neighbor cells instead of all neighbor cells by the fuzzy logic. Based on the results of simulations, we know that the following details. Firstly, the fuzzy multicast method significantly reduces the static network bandwidth usage and also provides linguistic guarantee for disruption free service. Secondly, the probability of disruption free service is determined both by the linguistic QoS of mobile users and the direction of mobile hosts. Specially, the probability of disruption free service is affected primarily by the linguistic QoS of mobile users. Accordingly, we conclude that the fuzzy multicast provides excellent differential service for disruption free service with specifying linguistic QoS of mobile users.
