Small world characteristics (SWC) have been observed and studied in a wide range of disciplines such as social, biological, electrical and computer networks. However, the significance of SWC in wireless sensor network (WSN) applications has hitherto not been investigated. This work investigates the significance of introducing SWC in a conventional WSN for improving the accuracy of WSN node localization...
A novel method for binaural source localization using a HRTF data model with enhanced frequency diversity is proposed in this work. The method proposed herein is developed in the frequency domain and enhances the directional information in the sound signal for efficient broad band sound source localization even under conditions of low SNR. The directional information is enhanced by cancelling the...
In this paper, a method for node localization in a novel small world - wireless sensor network (SW-WSN) is proposed. A SW-WSN is created by introducing small world characteristics into a conventional wireless sensor network (WSN). Introduction of long-ranged links between selected nodes in a WSN reduces average path length (APL) of the network without affecting the clustering coefficient (CC) significantly...
