摘　　要：This paper presents an analytical model of group based hand-off management based on bird flocking behavior. In the proposed scheme, a number of mobile devices form a group if these devices move together for a long time duration. Although call delivery or call generation are performed individually, hand-off is performed in a group. Dynamic group formation, group division and group merging methods are proposed in this paper. From the simulation results it is demonstrated that approximately 75%, 65% and 90% reduction in power, cost and latency consumption can be obtained respectively using group hand-off management. Thus the proposed scheme is referred as green, economic and fast hand-off strategy. In this paper instead of a macrocell network, a microcell-femtocell network is considered as the transmission power of a microcell or a femtoeell base station is much less than a macrocell base station. Simulation results present that the microcell-femtocell network achieves approximately 25-55% and 35-55% reduction in power transmission, and 50-65% and 15-45% reduction in path loss than only a macrocell network and macrocell-femtocell network respectively. Thus mierocell-femtocell network is a power-efficient network.
