Restless Bandits with Constrained Arms: Applications in Social and Information Networks
Varun Mehta, Rahul Meshram, Kesav Kaza +1
We study a problem of information gathering in a social network with dynamically available sources and time varying quality of information. We formulate this problem as a restless…
Sequential Decision Making with Limited Observation Capability: Application to Wireless Networks
Kesav Kaza, Rahul Meshram, Varun Mehta +1
This work studies a generalized class of restless multi-armed bandits with hidden states and allow cumulative feedback, as opposed to the conventional instantaneous feedback. We ca…
Multi-armed Bandits with Constrained Arms and Hidden States
Varun Mehta, Rahul Meshram, Kesav Kaza +1
The problem of rested and restless multi-armed bandits with constrained availability of arms is considered. The states of arms evolve in Markovian manner and the exact states are h…
Symbiotic Cognitive Relaying with mobile Secondary nodes in Cognitive Radio Networks
Prakash Chaki, Gouri Nawathe, Aaqib Patel +2
In a Symbiotic Cognitive Relaying (SCR) scenario, the Secondary users(SU) nodes can act as multihop relays to assist the communication between Primary User(PU) nodes in the case of…
Capacity and Spectral Efficiency of Interference Avoiding Cognitive Radio with Imperfect Detection
Aaqib Patel, Md. Zafar Ali Khan, S. N. Merchant +1
In this paper, we consider a model in which the unlicensed or the Secondary User (SU) equipped with a Cognitive Radio (CR) (together referred to as CR) interweaves its transmission…
