Title : Broadband Over Power Line Technology-A Critical Analysis In Indian Context

Author Name : Lipi K. Chhaya

Synopsis :

Broadband over power line technology provides high speed broadband Internet access over conventional electrical power lines.Broadband over power line is a recently commercialized technology that allows broadband Internet (using Internet Protocol - IP) to be communicated over the power grid at speeds ranging from 4Mbps to 145Mbps for delivery of data traffic and applications to homes and businesses on a shared basis. It is gaining attention due to ease of deployment, cost effectiveness and high speed reliable services. BPL is already deployed in many countries like U.S, Africa, Europe and Middle East. In India, IIIT Allahabad has undertaken a project in collaboration with Corinex Communications Canada to implement a prototype of BPL for University campus and nearby villages. This paper shows the critical analysis of Broadband over power line technology deployment in Indian context.

Title : Joint Optimization Of Physical Layer Handover Parameters In Wimax Networks 

Author Name : Edwin Winston, K.S. Shaji 

Synopsis :

Mobility is the most important feature of a wireless cellular communication system. The IEEE standard 802.16e-2005 provides enhancements to IEEE standard 802.16-2004 to support subscriber stations (SS) moving at vehicular speeds. Although the IEEE 802.16e standard proposes to tackle this problem, the disruption time (DT) of handover is still too long to overcome the maximum delay time of real-time services such as VoIP and video bit streaming.  To deal with these problems, we propose to optimize the decision taking algorithm parameters Modulation/coding, Scanning Threshold and Base Station & Mobile Station Antenna gain. The performance of our decision taking algorithm is evaluated using OPNET simulations.

Title : Silicon Based MEMS Pressure Sensor for Enhancing the Sensitivity and Linearity 

Author Name : Maflin Shaby, Vimala Juliet

Synopsis :

This paper presents a structural analysis of MEMS Pressure sensor. The diaphragm of the Pressure was made of silicon. Different diaphragm shape, pressure range, the positioning of resistors in the diaphragm and the length and width of the resistors were considered during the analysis. A simulation programs were developed to predict the sensitivity and linearity behavior of the piezoresistive pressure sensor. The output response of the pressure sensor was also found as a function of temperature and pressure. The analysis showed that sensitivity and linearity are influenced by diaphragm thickness and length of the sensing resistor.

Title : Analog To Digital TV Migration In Ghana

Author Name : ABDUL-MUMIN SALIFU

Synopsis :

This paper is to investigate the transitioning from analogue broadcasting to digital broadcasting in Ghana and how Ghanaians will easily adapt to it. The migration from analog television broadcasting to digital television broadcasting is a very complex and sensitive process which will affect almost every Ghanaian including the government, broadcasters, signal distributors, stakeholders and consumers. The objective of this paper is to investigate the transitioning from analogue broadcasting to digital broadcasting in Ghana and how Ghanaians will easily adapt to it. This research work give an overview of analog and digital broadcasting and the benefits stakeholders will drive from migrating from analog to digital broadcasting. The research further came out with some vital statistics about the public knowledge of the migration process and public usage of broadcasting in Ghana. Based on the findings some implications were drawn and recommendation given.

Title : A Novel Polygon Antenna Scanned Array for Cognitive Radio 

Author Name : siva sundara pandian s, C.D Suriyakala 

Synopsis :

This paper presents about a new antenna design of ultra wide band antenna for cognitive radio wireless communication. This antenna consists of polygon on a printed circuit board; ground plane. This antenna was simulated in ADS (Advanced Design System) Momentum. The feeding point is the micro strip line and to this attached the polygon structure. A ultra wideband antenna is necessary in order to achieve the channel sensing which should possess an Omni directional radiation pattern. The ultra wide band antenna covers a spectrum from 5GHz to 12GHz for channel sensing. The resonant frequencies of the antenna are 7GHz and 9.77GHz.
