Suppose that two senders each obtain one share of the output of a classical, bivariate, correlated information source. They would like to transmit the correlated source to a receiver using a quantum multiple access channel. In prior work, Cover, El Gamal, and Salehi provided a combined sourcechannel coding strategy for a classical multiple access channel which outperforms the simpler “separatio...

In this paper, we study the decentralized parallel multiple access channel (MAC) when transmitters selfishly maximize their individual spectral efficiency by selecting a single channel to transmit. More specifically, we investigate the set of Nash equilibria (NE) of decentralized networks comprising several transmitters communicating with a single receiver that implements single user decoding. ...

In this paper we determine bounds of the capacity region of a two-user multiple-access channel with Rayleigh fading when neither the transmitters nor the receiver has channel state information (CSI). We assume that the fading coefficients as well as the additive noise are zero-mean complex Gaussian and there is an average power constraint at the channel input for both senders. Results that we g...

In this paper we analyze the delay performance of an opportunistic multi-channel medium access control scheme and compare it to that of the corresponding single channel MAC scheme. In the opportunistic multi-channel MAC scheme, we assume that the pair of sender/receiver is able to evaluate the channel quality after a certain amount of channel sensing delay and to choose the best one for data co...

A multichannel reservation-based channel-access protocol is investigated in this paper. Under this protocol, one channel is used to exchange reservation messages and the remaining channels are used for information-bearing trajjic. The performance of this scheme is compared to that of a singlechannel reservation-based protocol. A simple contentionbased slotted-Aloha protocol is also considered. ...

In this paper, we present a routing and channel assignment protocol for multi-channel multi-hop wireless networks. We view a multi-hop network as an extension to infrastructure networks, where a mobile host may connect to an access point using multi-hop wireless routes, via other mobile hosts or wireless routers. The access points are configured to operate on one of multiple available channels....

We evaluate the performance of an opportunistic multi-channel medium access control protocol and compare it to that of the corresponding single-channel MAC (S-MAC) and a nonopportunistic multi-channel MAC (M-MAC). We do this in three different settings: (1) an ideal scenario where no control channel is used and no sensing delay is incurred, (2) a more realistic scheme where users compete for ac...

In this paper, we present a routing and channel assignment protocol for multi-channel multi-hop wireless networks. We consider a multi-hop network, where a mobile host may connect to an access point using multi-hop wireless routes, via other mobile hosts or wireless routers. Also, we consider a multi-channel network where multiple non-overlapping (orthogonal) channels are available, and each ho...

The principal objective of this work is to show that ubiquitous communication, in a vehicular communication environment, is possible by exploring the existing radio access networks. Proper channel modeling is essential to utilize current network infrastructure. An overview of basic channel propagation models and fading models are presented here. Then vehicle-to-vehicle
