A Highly Robust Sparse Fractal Array
Kretika Goel, Monika Aggarwal, Subrat Kar
The term fractal refers to the fractional dimensions that have recursive nature and exhibit better array factor properties. In this article, we present a new class of sparse array…
A High Resolution Optimum 2D Coprime Planar Array
Kretika Goel, Monika Aggarwal, Subrat kar
Designing a new class of rectangular two-dimensional sparse array to enhance the signal resolving capabilities with a limited number of sensors has always been a challenge. We expl…
RSSI-based Secure Localization in the Presence of Malicious Nodes in Sensor Networks
Bodhibrata Mukhopadhyay, Seshan Srirangarajan, Subrat Kar
The ability of a sensor node to determine its location in a sensor network is important in many applications. The infrastructure for the location-based services is an easy target f…
Person Identification using Seismic Signals generated from Footfalls
Bodhibrata Mukhopadhyay, Sahil Anchal, Subrat Kar
Footfall based biometric system is perhaps the only person identification technique which does not hinder the natural movement of an individual. This is a clear edge over all other…
Experimental Investigation of Optimum Beam Size for FSO Uplink
Hemani Kaushal, Georges Kaddoum, Virander Kumar Jain +1
In this paper, the effect of transmitter beam size on the performance of free space optical (FSO) communication has been determined experimentally. Irradiance profile for varying t…
Performance Analysis of an Improved Graded Precision Localization Algorithm for Wireless Sensor Networks
Sanat Sarangi, Subrat Kar
In this paper an improved version of the graded precision localization algorithm GRADELOC, called IGRADELOC is proposed. The performance of GRADELOC is dependent on the regions for…
Location Estimation with Reactive Routing in Resource Constrained Sensor Networks
Sanat Sarangi, Subrat Kar
Routing algorithms for wireless sensor networks can be broadly divided into two classes - proactive and reactive. Proactive routing is suitable for a network with a fixed topology.…
