HBCCS Technique for Optimal Resource Allocation in OFDMA-LTE System to Macro-FEMTO Cell Mitigate Interference

The femtocell is the wireless access point which encourages the cellular reception capability in building a base station which consumes low power and short range communication with low cost. The signal strength of the cell is high due to the capacity of short-range communication between the sender and receiver. The interference mitigation is the new challenge in the femtocell networks. So in between the macro and femtocells, the cross-tier interference are the major issue in orthogonal frequency division multiple access-long term evolution system. The interference mitigation in femtocell network system can be managed through the novel optimization hybrid bee colony cuckoo search algorithm. The vital role of macro and femtocell user is the power and bandwidth allocation. The power values are updated through the algorithm to allocate the femto and macro cell users. Then the performance of spectral efficiency, throughput, and signal to interference noise ratio and outage probability is measured and compared with the existing algorithm like cuckoo search, artificial bee colony, genetic, and particle swarm optimization algorithms
