A Wireless Sensor Network (WSN) is a form of ad hoc network consisting of tens to thousands of distributed autonomous tiny computing devices each equipped with sensors, a wireless radio, a processor, and a power source. Because of military applications such as battlefield surveillance the wireless sensor networks are originally developed. Since the network life ...

Distributed denial of service is major security threat that has been increasing today. If network size increases, the security threats problems becomes more severe. Therefore, intrusion prevention/detection becomes mandatory. The system differentiates the traffic coming from the authorized user and an intruder. The introduction of IPS aims at preventing the attack as far away from ...

Cognitive Radio (CR) is a promising technology which deals with using vacant spectrum of licensed frequency band opportunistically. In CR network, route construction must not affect the transmission of primary user activity. In CR technology challenge of maintaining optimal routes arises due to PU activity and mobility of spectrum resources i.e. CR users. Maintaining optimal ...

Web usage mining is to discover and extract useful information. It helps in better understanding and better serves the needs of web-based applications. The data should be preprocessed to improve the efficiency and ease of the mining process. The proper analysis of web log file is beneficial to manage the websites effectively for administrative and ...

Emergence of modern techniques for scientific data collection has resulted in large scale accumulation of data pertaining to diverse fields. Conventional database querying methods are inadequate to extract useful information from huge data banks. Cluster analysis is a primary method for database mining. It is either used as a stand-alone tool to get insight into ...

Cable operators have collection agents to collect the money from their customers. The collection agents cheat in the process. Sometimes they do not give the money collected to the cable operator. The authors are providing a solution to this problem. They are going to make a database with all the customer information stored in it. ...

Notice boards are a common occurrence in variety of institutions which people come across on a daily basis. In the current scenario the notice/advertisement boards are being managed manually. There is a long process involved in order to put up notices on the notice board. This wastes a lot of resources like paper, printer ink, ...

In this paper, the authors propose the application of cryptography algorithm to ensure secure communication across the virtual networks. In cryptography, encryption is the process of encoding messages or information in such a way that hackers cannot read it. In an encryption scheme the message or information is encrypted using an encryption algorithm, turning it ...

WiMAX has approved a non-cellular telecommunication technology, as a big part of the IEEE 3G standards for the 2.6GHz frequency band by the International Telecommunications Union (ITU), so the same way, WiMAX can be considered as an earliest version of the next generation of mobile wireless systems. Under the same technology evolution of various different ...

Wireless networks of sensor nodes are envisioned to be deployed in the physical environment to monitor a wide variety of real-world phenomena. Wireless Sensor Networks (WSNs) are becoming popular in military and civilian applications such as surveillance, monitoring, disaster recovery, home automation and many others. WSN demand low power and low cost transceiver design. The ...
