Wireless Networks

Wireless communications allow different new applications of computer networks, such as mobile ad hoc networks, wireless mesh networks, and sensor networks. Wireless networks come with the great advantage of user mobility. Where infrastrucure is used, wireless networks provide for lower cost. Nevertheless, wireless communications are prone to much higher bit error probabilities than wired networks; depending on the application, energy consumption is a critical issue of wireless networks. Security is a very important research topic of wireless networks, given the decentralized architecture of different wireless applications and the very open nature of the wireless medium. In this research theme, different aspects of wireless networks are investigated.
