Cooperation-based Multi-hop Routing Protocol for Cognitive Radio Networks

In the scope of cognitive radio networks, typical routing protocols avoid areas that are highly congested with primary users, leaving only a small fragment of available links for secondary route construction. In addition, wireless links are prone to …

Primary User-Aware Optimal Discovery Routing for Cognitive Radio Networks

Routing protocols in multi-hop cognitive radio networks (CRNs) can be classified into two main categories: local and global routing. Local routing protocols aim at decreasing the overhead of the routing process while exploring the route by choosing, …

Cost-Effective Data Transfer for Mobile Health Care

In this paper, we introduce the novel concept of cost-effective mobile health care which leverages the multiple wireless interfaces onboard most mobile phones today. First, we study the problem of uploading medical data using the “least cost” radio …
