Growing number of vehicles on the road unavoidably leads to increasing amount of accidents. As a result, Vehicular Ad-hoc Network (VANET) has been proposed with the aim of preventing accidents and increasing road safety. Based on the currently proposed Dedicated Short-Range Communication (DSRC) technology for Wireless Access in Vehicular Environment (WAVE)(More)
One of the crucial challenges experienced by Wireless Sensor Networks (WSNs) is the increasing number of devices sharing the limited spectrum of the ISM band. As a result, a new concept of Cognitive Wireless Sensor Networks (CWSNs) has been proposed in order to achieve reliable and efficient communication via spectrum awareness and intelligent adaption.(More)
With the increasing number of devices sharing the 2.4 GHz ISM band, coexistence problem becomes one of the major issues experienced by Wireless Sensor Networks (WSN). Cognitive Wireless Sensor Networks (CWSNs) has been proposed in order to achieve reliable and efficient communication via spectrum awareness and intelligent adaption. The learning and decision(More)
Interference is one of the major factors influencing system performance of Wireless Sensor Networks (WSNs). This issue needs a serious attention, since WSNs are typically operating on the shared and unlicensed spectrum band. In other words, interference may not be controllable especially under the coexistence of devices operating with different standards(More)
