In recent past, researchers have shown a lot of interest in Under Water Sensor Networks (UWSNs) because of its application in wide range of domains. UWSN, actually a sub body of Wireless Sensor Networks (WSN), facilitate with radio communication with high-precision of information to a sink node from any of the source node. The Role of any-casting is of significant importance in the context of routing...
Nonlinearities in wireless communication channels foil the performance of the communication systems either at the transmitter or receiver end. This paper explains the concept of the transmitter-side nonlinearities that are induced by the High Power Amplifiers (HPA), the final stage at the transmitter side of the communication system. HPA nonlinearities create in-band and out-of-band distortions in...
Three different designs of a dual band patch antenna have been investigated in this paper. By using u-slot patch geometry dual band operation has been obtained. The patch antenna has been designed and simulated in CST Microwave Studio. By studying the antenna parametrically, it has been observed in CST Microwave Studio how the antenna characteristics vary with the variation of its different parameters...
Intrusion prevention is one of the fundamental requirements for a network to be secure. Investing on intrusion prevention forbade its use for securing many networks. This study proposes a very basic way to prevent intrusions without any additional cost. Snort is a free open source IDS, which we have integrated with a Cisco router to prevent intrusions. Cisco routers are very common in today's networks...
