Cognitive Radio (CR) can be used as a solution to current unbalanced spectrum utilization. The cognitive ad hoc network can take advantage of dynamic spectrum access and spectrum diversity over wide spectrum. It could achieve higher network capacity compared to traditional ad hoc networks, thus supporting bandwidth-demanding applications. Mobile ad-hoc networking has gained an important ...

Wireless sensor networks sense various kinds of information process them locally and communicate it to the outside world via satellite or Internet. In the near future, sensor networks will play a major role in collecting and disseminating information and the sensors will be shared by multiple applications and gather heterogeneous data of different priorities. With ...
