Multi-Channel Sensing and Access Game: Bayesian Social Learning with Negative Network Externality

Chinese Restaurant Game - Part I: Theory of Learning with Negative Network Externality

In a social network, agents are intelligent and have the capability to make decisions to maximize their utilities. They can either make wise decisions by taking advantages of other agents’ experiences through learning, or make decisions earlier to avoid competitions from huge crowds. Both these two effects, social learning and negative network externality, play important roles in the decision p...

Joint Design for Opportunistic Spectrum Access with Multi-Channel Sensing

Consider a spectrum of N orthogonal channels licensed to a slotted primary network. Let Sn(t) ∈ {0 (busy), 1 (idle)} denote the occupancy of channel n in slot t. We assume that the spectrum occupancy S(t) ∆ = [S1(t), . . . , SN(t)] follows a discrete-time homogeneous Markov process with finite state space S ∆ = {0, 1} and known transition probabilities {Ps,s′}s,s′∈S, where Ps,s′ ∆ = Pr{S(t+ 1) ...

Prioritized Access in a Channel-Hopping Network with Spectrum Sensing

We investigate the performance of priority-based access in a channel-hopping cognitive network, in particular the interaction between the number of packets each node is allowed to send in a single transmission cycle and the penalty coefficient that determines the amount of sensing to be done upon a successful transmission. Our results indicate that giving higher bandwidth allocation to low prio...

On Myopic Sensing for Multi-Channel Opportunistic Access

We consider a multi-channel opportunistic communication system where the states of these channels evolve as independent and statistically identical Markov chains (the Gilbert-Elliot channel model). A user chooses one channel to sense and access in each slot and collects a reward determined by the state of the chosen channel. The objective is to design a sensing policy for channel selection to m...
