Wireless sensor networks are emerging technologies that are diverse on energy consumption from different aspects. In the task mode, energy consumption of sensor nodes is categorized in, data packet transmitting, data processing and idle mode. Fundamentally, higher power is required and utilized at the time of data receive as comparing to idle mode. However, power ...

The service oriented architecture supports reusable components. Component reusability is one of the important features while designing Web services for reuse. The reusability is an ideal and key factor to improve the quality and production rate of software. It becomes very helpful for quality assurance, if such quality parameters can be quantified. Non-functional quality parameters ...

Cloud is the recent emerging technology in all aspects. The basic concern with the usage of this cloud Technology is security. Security poses a major drawback with data storage, resource utilization, virtualization, etc. In the highly competitive environment the assurances are insufficient for the customers to identify the trust worthy cloud service providers. As a ...

Voice over IP (VoIP) is commonly known as phone service over the Internet. Any service using public IP network requires certain extent of security. Demand for security in VoIP technology is increasing. VPN is one of the commonly used methods to secure VoIP traffic. In this paper, the authors simulated behavior of a VoIP communication ...

Computational paradigm has been revolving round cloud computing and its offshoots for some time and till the authors see a breakout resulting in a breakthrough technology driven by advances in microelectronics and material technology. Till they experience a radically efficient technology for computation it is worth juxtaposing the virtues of cloud computing and market’s longing ...

Mobile app reviews are gaining importance as a crowd source to improve the quality of mobile apps. Mobile app review systems are providing a platform for users to share their experiences and to support in decision making for a certain app. Developers, on the other side, are utilizing the review system to get real-life user ...

Converge cast communication is used in many sensor applications. The flow of data in converge cast routing is from many to one i.e. many sensory nodes sense the data and send through parent child relation to the root node or sink node. Converge cast routing is always followed by broadcasting. In broadcast communication is from ...

Nodes in Mobile Ad hoc NETwork (MANET) are forming a dynamic topology by that the nodes are continuously change their location and also the nodes functioning is dependent on the limited battery capacity that is called energy. The dynamic behavior of network connection is not maintained for long time. All nodes in network are energy ...

MANET (Mobile Ad hoc NETwork) is evolved through various characteristics such as shared media, this property make routing protocols vulnerable. AODV (Ad hoc On-demand Distance Vector) is a reactive routing where each intermediate node cooperates in the process of route discovery. In this case, the node that behaves as malicious exploit the malfunction of specified ...

In this paper, a few methods for anomaly detection in computer networks with the use of time series methods are proposed. The special interest was put on Brown’s exponential smoothing, seasonal decomposition and naive forecasting and Exponential Moving Average method. The validation of the anomaly detection methods has been performed using experimental data sets and ...
