The next-generation wireless network is going to have highly dense, small cell structure with the huge number of Device-to-Device (D2D) communication enabled mobile devices. The dense deployment of the heterogeneous network architecture is expected to fulfill the user’s growing data demand, consume lower power and have a much lower latency. Such 5G cellular networks will have a multi-tier architecture with various cell size consisting of macrocells, D2D communication networks and different types of small cells for better quality of services to the users. The huge deployed heterogeneous networks create problems such as interference management, non-uniform cell capacity with not uniform users connectivity and cell coverage areas. In order to maximize the data rate of users, resource allocation and interference minimization problem with non uniform capacity is formulated as an NP-hard problem. Further, to solve the resource allocation problem in efficient computation cost, we propose stable matching based distributed algorithm for heterogeneous 5G networks. Through extensive theoretical and simulation analysis, we have shown the effect of different parameters on the resource allocation objectives.

Day by day there is an increase in the number of mobile users, consequently we see an evolution in the cellular networks. Starting from the first generation in 1980 we are now awaiting the arrival of 5th generation (i.e., 5G) networks. 5G communication network aims at higher capacity than current 4G (up to 10 Gbps), allowing a higher density of mobile broadband users, supporting more reliable Device-to-Device (D2D) and massive small cell networks......

Summer research project, IIIT-D, 2018
We took variant of the stochastic multi-armed bandit problem, where multiple players simultaneously choose from a set of arms and then resolved many drawbacks like collision, prior knowledge of users, quasi stationary reward distribution (change detection), etc.
