Traffic-Aware Green Cognitive Radio

See publicationCognitive Radio Network (CRN) has emerged as an effective solution to the spectrum under-utilization problem, by providing secondary users (SUs) an opportunistic access to the unoccupied frequency bands of primary users (PUs). Most of the current research on CRN are based on the assumption that the SU always has a large amount of data to transmit. This leads to the objective of SU throughput maximization with a constraint on the allowable interference to the PU. However, in many of the…
Cognitive Radio Network (CRN) has emerged as an effective solution to the spectrum under-utilization problem, by providing secondary users (SUs) an opportunistic access to the unoccupied frequency bands of primary users (PUs). Most of the current research on CRN are based on the assumption that the SU always has a large amount of data to transmit. This leads to the objective of SU throughput maximization with a constraint on the allowable interference to the PU. However, in many of the practical scenarios, the data arrival process of the SU closely follows an ON–OFF traffic model, and thus the usual throughput optimization framework may no longer be suitable. In this paper, we propose an intelligent data scheduling strategy which minimizes the average transmission power of the SU while maintaining the transmission delay to be sufficiently small. The data scheduling problem has been formulated as a finite horizon Markov Decision Process (MDP) with an appropriate cost function. Dynamic programming approach has been adopted to arrive at an optimal solution. Our findings show that the average transmitted power for our proposed approach can be as small as 36.5% of the power required for usual throughput maximization technique with insignificant increase in average delay.

Game Theory in Wireless Networking
- Present
Successfully implemented concepts from Game theory to derive an iterative waterfilling algorithm for noncooperative scheduling in heterogeneous networks. A new sequential optimization approach has been developed to solve an otherwise intractable game. The algorithm developed is a generalization of the famous Waterfilling algorithm that is applicable for a single player scenario. The convergence proof is under consideration.

Long Term Average Rate Optimization in Cloud Radio Access Network
-
This project centers around an upcoming communication environment, known as Cloud Radio Access Network (CRAN). In such a network, multiple Base Stations (BSs) cooperate among themselves in order to improve the coverage of the network. Optimal transmission strategy for one such downlink CRAN has been obtained in this project.

Interference Cancellation in Wireless Duplexer
-
An online signal processing block was designed for improving isolation in a duplex radio. The DSP block would employ the non-correlatedness of transmitted noise to estimate an unknown channel gain, which would otherwise require a pilot signal.
