Multi-Radio Channel Detecting Jamming Attack Against Enhanced Jump-Stay Based Rendezvous in Cognitive Radio Networks
Rendezvous problem has been attracting much attention as a fundamental process to construct the Cognitive Radio Network (CRN). Many elegant algorithms have been proposed to achieve rendezvous on some common channel in a short time, but they are vulnerable to the jamming attacks where a jammer may exist listening or blocking the channels [13]. In this paper, we propose the Multi-Radio Channel De...
متن کاملPliable Cognitive MAC for Heterogeneous Adaptive Cognitive Radio Sensor Networks
The rapid expansion of wireless monitoring and surveillance applications in several domains reinforces the trend of exploiting emerging technologies such as the cognitive radio. However, these technologies have to adjust their working concepts to consider the common characteristics of conventional wireless sensor networks (WSNs). The cognitive radio sensor network (CRSN), still an immature tech...
متن کاملCognitive Radio Network Application Radio
Application of cognitive radios as the wireless terminals in ad hoc networks in emergency situations has distinct advantages. Better bandwidth, interoperability, avoidance of interference, and ant-jamming capabilities are a few such advanta This paper deals with ad hoc networks incorporated with cognitive radios, which acts as wireless terminals, that can be used in emergency situations and can...
متن کاملOblivious Rendezvous in Cognitive Radio Networks
Rendezvous is a fundamental process in the operation of a Cognitive Radio Network (CRN), through which a secondary user can establish a link to communicate with neighbors on the same frequency band (channel). The licensed spectrum is supposed to be divided into N non-overlapping channels and most previous works assume all users have the same label for the same channel. However, this might be im...
متن کاملEasitest: a Multi-radio Testbed for Heterogeneous Wireless Sensor Networks
In this paper, we propose EasiTest, a multi-radio testbed for heterogeneous wireless sensor networks (WSN). Two types of sensor nodes, specifically, high speed multi-radio node (EZ271) and low speed single radio node (EZ521) are developed. An administration platform is provided to monitor and control the testbed. EasiTest enjoys high flexibility, powerful processing capability and ease of expan...
