Congestion Control for Radio Networks

2015
Nowadays, we have witnessed an exponential growth of the traffic generated by users in mobile communications networks. This need for a greater capacity in mobile networks raises problems for operators, because the demand for network capacity is not always accompanied by the evolution of the available technologies.

A Survey on Cognitive Radio Networks

2010
The limitation of the spectrum bands is a major bottleneck for the development of next generation wireless networks. Cognitive Radio (CR) aims at improving the spectrum utilization by taking advantage of licensed but currently unused spectrum. CR has broad applications including dynamic spectrum access and interference management, which will largely ...

Asynchronous Broadcast in Radio Networks

2004
We study asynchronous packet radio networks in which transmissions among nodes may be delayed. We consider the task of broadcasting a message generated by the source node. The timing of arrivals of messages is controlled by adversaries. We consider three different adversaries.

On selection problem in radio networks

Proceedings of the twenty-fourth annual ACM symposium on Principles of distributed computing, 2005
A selection problem is among the basic communication primitives in networks. In this problem at most k participating stations have to broadcast successfully their messages. This problem is especially important in packet radio networks, where simultaneous transmissions of many neighbors result in interference among delivered messages.

Radio Networks with Reliable Communication

2005
Problems of secure communication and computation have been studied extensively in network models, for example, Franklin and Yung have studied secure communications in the general networks modeled by hypergraphs. Radio networks have received special attention in recent years.

On Efficient Gossiping in Radio Networks

2010
A communication network is very often modelled as a graph of connections in which the nodes exchange information (messages) via (un)directed links. An associated communication protocol determines the way the messages are exchanged. Among the most popular network models are: (1) the message passing model in which a node in one round can inform all its ...
