Cognitive Radio technology allows the unlicensed users to access the free licensed frequency band opportunistically to address the problem of the scarcity of unlicensed radio spectrum and for better utilization of the licensed radio spectrum. There was some problem in the cognitive radio systems such as Inter Symbol Interference and low data rate. To achieve the higher data rate and reduce the problem...
Machine Learning is the field of computer science that learns from data by studying algorithms and their constructions. In machine learning, predictions can be made by using certain algorithms for specific inputs. In this paper important classification and clustering algorithms are discussed which can be further applied to BE (Information Technology). Third Semester to evaluate student's performance...
The monitoring of network traffic helped in ensuring the integrity of the data inside the network. Software defined networking (SDN) provided a platform for network administrators to easily apply monitoring policies on the networks. SDN's centralized control and programmability features aids in efficient monitoring of network traffic in distributed environments. Various efficient anomaly detection...
Monitoring and measurement of network traffic flows in SDN is key requirement for maintaining the integrity of our data in network. It plays a vital role in management task of SDN controller for controlling the traffic. Anomaly detection considered as one of the important issues while monitoring the traffic. More efficiently we detect the anomalies, easier it will be for us, to manage the traffic...
A Mobile Ad hoc Network (MANET) comprises nodes which are wireless. These nodes communicate via radio waves. MANET has a dynamic topology due to which there is a random movement of nodes. When two nodes move out of range of each other, the link between them fails, leading to the need of finding new routes. To find the route, broadcasting is the basic and effective technique used. But there is a broadcast...
Mobile Ad hoc network comprises of many nodes which interact with each other through wireless links. It is infrastructure less in nature, due to which attackers can easily attack on the network from any side. There are many attacks which ruin the communication among the nodes of network. Among those attacks there is a Sybil attack that causes severe hazards to the network. Sybil attack is an attack...
Image segmentation is one of major image processing activity used to identify a specific pixel area over the image. In this presented, an improved segmented approach is presented to recognize the object in a scene or image. Such kind of segmentation is helpful to identify the component object in a scene or the image. The presented work is based on the Mathematical analysis to identify the object position...
