Abstract

Kudarihal and his co-author Menghal study the aspects of maintaining equipments in remote areas with timely and accurate prediction of failures. For a comprehensive health monitoring of DG (Diesel Generator) Set, the microcontroller based wireless sensor network system has been developed. The ATMEL AT89S52 is a powerful microcontroller which provides a highly-flexible and cost-effective solution to many embedded control applications and provide interface with main circuits and various feedback signals.It is accurate, relatively inexpensive and easy to use.

Abstract

Mary Juliet and her co-author Jayashriproposea new methodology to determinineinterleaveralong with its correlation analysis. They also analyze the Multiple Access Interference (MAI) performance of new interleavers using peak correlation analysis. Collision probability of an interleaver is achieved by performing correlation analysis. In OFDM-IDMA, IDMA (Interleave Division Multiple Access) is a novel technology that replaces the drawbacks of existing Code Division Multiple Access (CDMA) technique. The clockwise interleaver has a user specific cross correlation 0.27 which is nearly zero. This indicates that the collision between two interleavers is nearly zero.

Abstract

Milad Hajmirzaei proposes an efficient algorithm called IMAS (Improved Multi slotted scheme with Assigned Slots) algorithm which overcomes the problem caused by Tag collision. During the transmission of information from one reader, the collision occurs when more than one tag transmit its ID to reader simultaneously. When more than one tag with a same prefix respond in a slot, the collision will be detected by reader. More than 200 tags are used for experiment and the collision is less IMAS.

Abstract

Z.Mary Livinsa and S.Jayashri deliberate a Received Signal Strength Indicator(RSSI) to estimate the distance between two sensor nodes in a WSNs that ingests the built in RSSI circuit board inside the sensor’s transceivers chipsets. AmicaZ platform is used which is based on the radio chip CC2420 that operates in 2.4GHZ band using an effective data rate of 256Kbps.The experiment repeated for 100 times and the error range is an average of 2.034m.

Abstract

Sweta Arya presents a novel method to find out the desired file in a partially structured local peer-to-peer network to authenticate each entry of data which are accessed by the user for future. A technique is evaluated to increasing the efficiency of search scheme by replicating the database at certain selected nodes which increase the availability of data. Data is replicated at the query node and become available for future transaction between peers. The application is designed with ASP.net in frontend and SQL server as backend. Speed of transfer of data is also improved due to efficient structuring in the database of system.
