TCP (Transmission Control Protocol) is a reliable transmission control protocol. One of primary elements of TCP is to transmit information in a secured way over a system. To this end, TCP utilizes a congestion control mechanism. In the TCP congestion control mechanism, congestion occurring during data transmission is detected from a data packet loss to ...

Wireless has opened a new and exciting world for many of the people. Its technology is advancing and changing every day and its popularity is increasing. The biggest concern with wireless, however, has been security. Threats to WLAN are numerous and potentially devastating. Security issues ranging from misconfigured wireless access points to session hijacking to ...

Cloud computing is an important model for delivering valuable business services to the cloud users. Cloud service consider as online storage where the data is remotely stored, managed and backed up based on pay per use. The user store their files in online and access them from anywhere via the internet. Data storage security is ...

In this paper, the authors present a method for creating a centralized database which will be used by both Android as well as web application. The Android application will be having its own local database (SQLite database) which will be used for offline storage of data. This offline data needs to be updated on the ...

The latest trend in handset design is slim smart phones that require small, thin, light weight and wideband multiband internal antennas. This trend poses two major challenges in designing a mobile device antenna: how to use a single antenna to cover all the required frequency bands and then how to make the same antenna small ...

In the contemporary world it is inevitable to minimize accumulation of exponential data. Apart from actual data, data formats are also growing. Explosive data growth by itself, does not accurately describe how data is changing; the format and structure of data are changing. Rather than being neatly formatted, cleaned and normalized data in a corporate ...

Cloud computing is a highly scalable and cost-effective infrastructure for running HPC, enterprise and Web applications. However, the growing demand of cloud infrastructure has drastically increased the energy consumption of data centers, which has become a critical issue. High energy consumption not only translates to high operational cost, which reduces the profit margin of cloud ...

In this paper, the authors propose a new secure e-voting protocol based on public-key encryption cryptosystem. This protocol is summarized in three processes: firstly, access control process which involves the identification and authentication phases for the applied citizens. Secondly, the voting process which will be done by ciphering the voter information using public-key encryption cryptosystem ...

Antenna with hexagonal fractal geometry using ultra wide band pattern is been discussed in this paper. The proposed antenna is fed with co-axial line and its structure depends on hexagonal fractal geometry wherever resonance frequency of antenna is a lowered using iteration technique, which is the repetition of motif over two or more scale sizes. ...

With increasing demands of Electronics products in the domain of the industrial & consumer application, it becomes necessary to come up with new ideas of electronic products. In the field of communication, present real-time communication audio transmission uses technologies like WiMAX, IEEE 802.11, 3G and Bluetooth. But audio-streaming through Bluetooth or radio waves have drawbacks ...
