Localization and communication are critical components for functioning autonomous robots. The infrastructure required or these operations commonly includes global positioning system (GPS) and easily recognizable and re-identifiable landmarks. Howe...
Research in the area of wireless sensor networks has seen unprecedented growth inthe last decade. Human deployable ad-hoc networks are being used to communicateessential information in places where there is no network or the network is destroyeddu...
Received radio frequency (RF) signal strength provides a cost-effective mechanism for distance estimation that is popularly used for range-based localization in wireless sensor networks (WSN). The typical method of determining sensor location usin...
The goal of this dissertation is to give the sufficient conditions for the absence of a.c.spectrum or existence of the pure point (p.p.) spectrum for the deterministic or random Schrodinger operators on the general graphs. For the particular situa...
