Improved performance analysis based on a novel hybrid access algorithm in femtocell networks

As the most potential way to improve the overall performance of the next generation wireless networks, femtocell has attracted much attention from vendors. To femtocell, hybrid access mode is a comprise access mode that operates between close access mode and open access mode. With this kind of access mode, not only the pre-registered users are able to access it, un-registered users could also gain benefits as long as there is available resources. In this paper, we propose a novel access control algorithm based on hybrid access mode. Simulation results show that this algorithm can decrease the outage rate of macro users without causing too much signaling overhead.
