Abstract
Enormous number of people use their smart phones and tablets to share photos, upload videos or send messages and download other information. These activities creates traffic load with lack of efficient spectrum utilization especially in dense areas. This paper investigates the performance gain that can be achieved by introducing a hotspot-slave configuration of nodes in densely populated areas. The proposed algorithm aims to maximize spectrum efficacy by iteratively clustering the nodes into hotspots and slaves and allocating resources. This approach does not require any additional infrastructure. Simulation results show that the proposed algorithm can significantly enhance the overall performance of the network by five times as compared to direct connection between the nodes and the base station, hence increasing the capacity of the cell.
