Throughput-Efficient Dynamic Coalition Formation in Distributed Cognitive Radio Networks
We formulate the problem of distributed throughput-efficient sensing in cognitive radio (CR) networks as a dynamic coalition formation game based on a Markovian model. The propose...

Pricing-based spectrum access control in cognitive radio networks with random access
Abstract—Market-based mechanisms offer promising approaches for spectrum access in cognitive radio networks. In this paper, we focus on two market models, one with a monopoly pri...

Structuring unreliable radio networks
In this paper we study the problem of building a connected dominating set with constant degree (CCDS) in the dual graph radio network model [4,9,10]. This model includes two types...

Performance Analysis of an Improved Graded Precision Localization Algorithm for Wireless Sensor Networks
In this paper an improved version of the graded precision localization algorithm GRADELOC, called IGRADELOC is proposed. The performance of GRADELOC is dependent on the regions fo...
