Abstract

In the field of ad hoc networks, maintaining connectivity and performing efficient energy communication between several mobile stations (MS), involves the use of optimized geo localization based routing algorithms. With multipath contribution, indoor location based on a direct time difference of arrival (TDOA) measurement can dramatically increase its budget error and asks for innovative solutions allowing accurate time-of-flight measurement. A natural way of exploiting multiband ultrawide-band (UWB) technology, a simple input and multiple output (SIMO) approach can lead to the measurement of an enhanced TDOA (E-TDOA) measurement for accurate positioning.
