Mobile networks that handle multicast communication services such as video conferencing, audio-conferencing, collaboration works, etc., require a kind of reliable and guaranteed point-to-multipoint communications. A multicast tree provides an efficient connectivity between the multicast mobile group members through base stations (point of attachment). Mobility of the hosts of a group necessitates maintenance of service quality multicast routes. This position paper proposes a fuzzy logic based multicast tree development for group communications based on fuzzy link parameters such as bandwidth, reliability, and delays. Multicast tree is recomputed based on the following cases: (1) whenever mobility of any of the group members away from point of attachment is detected, (2) new mobile host joining the group, (3) mobile host leaving the group, and (4) performance parameter degradation. The proposed work selects a reliable, bandwidth and delay aware multicast route, which provides the required Quality of Service (QoS) for applications in terms of reliability, guaranteed bandwidth and reduced delays.
