The emergence of novel wireless networking paradigms such as small cell and cognitive radio networks has forever transformed the way in which wireless systems are operated. In particular, the need for self-organizing solutions to manage the scarce spectral resources has become a prevalent theme in many emerging wireless systems. In this paper, the first(More)
Because the nodes of wireless sensor networks have the very limited energy, the main design goal for wireless sensor networks routing is how to improve energy ficiency. As a scheme to solve this problem, an energy equalizing routing algorithm (EERA) for wireless sensor networks was proposed. In the cluster head product phase, the candidates compete for(More)
In this paper, a novel spectrum association approach for cognitive radio networks (CRNs) is proposed. Based on a measure of both inference and confidence as well as on a measure of qualityof-service, the association between secondary users (SUs) in the network and frequency bands licensed to primary users (PUs) is investigated. The problem is formulated as(More)
With the widely adoption of smart mobile devices, there is a rapidly development of location based services. One key feature in providing the service is the crowdsourcing in which the principal obtains essential data from a large group of users, and inversely sharing the data based service with everyone for free. In this paper, we investigate the problem of(More)
