In this paper, the authors propose permission based Resource Management with Mutual Exclusion Algorithm for Mobile Ad-hoc NETworks (MANETs). To reduce the message cost, the algorithm uses the DAG (Directed Acyclic Graph) technique, which enforces MUTEX only among the hosts currently competing for the critical section. The authors propose mechanisms to handle doze and disconnections ...

The Multi-Carrier Code Division Multiple Access (MC-CDMA) is becoming a very attractive multiple access technique for high-rate data transmission in the future wireless communication systems. This paper is focused on reviewing different sub-carrier selection techniques for MC-CDMA system. It has been seen that appropriate subcarrier selection technique can significantly improve Bit Error Rate (BER) performance, ...

Universal Serial Bus (USB) devices are high transmission speed external devices. USB is the speediest external device available today. The access to USB is very simple, convenient and fast compared to other external devices such as CD, DVD, floppy drive, etc. Thus, USB have become most popular interface standard for hardware connection. But, from security ...
