Femtocells are aimed at providing high performance voice and data communications in and around the immediate home environment. Connected to the Operator’s mobile network over existing broadband connections in the home, femtocells have the potential to make indoor coverage for mobile communications truly pervasive while delivering additional benefits to both the Operator and end-user.In this paper, our main aim is to mitigate the interference generated when we go on insert the femto cell to a region containing more than one base station, the same causes the throughput of the base station to be decreasing when we go on inserting the femto cell to that region. we are going to employ the Coloring algorithm concept to mitigate the interference of the femto cell.The developed algorithm works by creating the interference graph by using the coloring algorithm , once we get the graph ,we apply the coloring algorithm to that ,and find the chromatic number of that graph, that chromatic number gives number of zones to be created in the femto cell region, once we divide the zones ,we send the users to particular zone depending upon SINR value and mean while we allocate the number of channels to that particular user.
hello sir
we trying create a scenario in matlab to mitigate interference between HetNets. Could you help us create a macrocell and femtocell in matlab.
thanks in advance.
Femtocells are small mobile telecommunication network stations that use clients' DSL or cable modem connections as backhaul. In addition, the femtocells are self-configuring and do not require a professional for installation. The devices themselves are about the same size as the current Wi-Fi access points. Many researchers have studied the femtocell business model and simulated performance and cooperation with the macro layer network. The femtocells specified in the 3GPP standards, known as Home NodeB, and other new components necessary to integrate the solution with the current networks are presented together with the different possible deployment configurations. Radio spectrum is limited; Therefore, from time to time developers have to come up with new solutions for the best efficient use of the spectrum. Various cell sizes are used such as microcells, femtocells, picocells and nanocells to increase user capacity in urban areas such as office buildings and shopping centers. Another method to improve coverage and capacity (2-3 times) is through the use of Distributed Antenna Systems (DAS) , which is an effective but costly method.
