Small Scale Networks (SCNs) such as femtocells are becoming increasingly popular among service providers as well as end customers. One major obstacle for SCNs is the management of the mobile users, resulting in frequent handovers which drastically reduce the overall performance. This work primarily focuses on providing a framework that reduces the number of handovers using Dynamic Virtual Cells by utilizing Multiple Multicasting Trees. Members of a virtual cell is defined by the multicast tree membership. Virtual cells can move with the mobile users and dynamically grow or shrink depending on the performance. Handovers occur only between different virtual cells belonging to different multicast trees, thus minimizing effective number of handovers.
