Quality of Service Improvement in Femto based Cellular Networks
A cellular network serve the high service demands of the indoor users it is very expensive to obtain macrocell coverage which results in requirement of new methods to solve problem of high capacity indoor coverage femto cell is one of the solutions. Deployment of femto cell networks embedded into macro cell coverage improves the coverage, capacity and quality of service in indoor environments. Due to its ad-hoc nature, the information about its density and location is not known a-priori. As femtos and macros share the same licensed spectrum, interference is one of the major problems observed and has to be mitigated. In this paper two existing channel allocation schemes such as opportunistic channel allocation scheme and orthogonal channel allocation scheme are discussed and their performance is compared to the proposed Max-SINR scheme. To reduce the interference further a self-organized and intelligent resource allocation is also proposed .Parameter such as average SINR experienced by each femto user is calculated by varying the percentage of active Femto cells in a network. Simulation results are carryout using MATLAB.
