A Review of Wireless Sensor Networks with Cognitive Radio Techniques and Applications

Routing Hole Handling Techniques for Wireless Sensor Networks: A Review

A Wireless Sensor Network consists of several tiny devices which have the capability to sense and compute the environmental phenomenon. These sensor nodes are deployed in remote areas without any physical protections. A Wireless Sensor Network can have various types of anomalies due to some random deployment of nodes, obstruction and physical destructions. These anomalies can diminish the sensi...

A Survey on MAC Protocols for Wireless Sensor Networks and Cognitive Radio Sensor networks Design

1. Introduction Wireless Sensor Networks (WSNs) has been a wide research topic for more than a decade. Typically, a WSN consists of spatially distributed autonomous sensors to monitor physical or environmental conditions. These sensors generate report over the network on the occurrence of any event. For a WSN to provide better reliability and improved lifetime, an efficient Medium Access Contro...

Spectrum Sensing Techniques for Cognitive Radio Networks: A Review

Cognitive radio is one of the most promising technologies that resolves the problem of inefficient spectrum utilization by enabling secondary user to opportunistically utilize the unused licensed bands. The prime functionality of cognitive radio is spectrum sensing in which presence of the primary usersis accurately detected. In this paper various spectrum sensing methods are presented together...
