Rapid advances in wireless ad hoc networks lead to increase their applications in real life. Since wireless ad hoc networks have no centralized infrastructure and management, they are vulnerable to several security threats. Malicious packet dropping is a serious attack against these networks. In this attack, an adversary node tries to drop all or partial received packets instead of forwarding them...
Cognitive Radio Network is a key solution to improve the spectrum utilization by enabling unlicensed users (Secondary Users) to exploit the spectrum in an opportunistic manner. Since secondary users are temporary visitors to the licensed spectrum (Primary Users), they should vacate the spectrum once a primary user reclaims it. This process has a large overhead for secondary users. This overhead includes...
In Cognitive radio Networks unlicensed users are temporary visitors to the licensed spectrum, they may be required to vacate the spectrum when a licensed user reclaims it. This process has a large overhead for secondary users. This overhead includes the time required for sensing the spectrum and finding new channels, communication delay between secondary transmitter/receiver as well as packet loss...
