Smartly Time of Arrival Interpretation in the Wide Band Ranging System

چکیده
In the field of sensor networks, impulse radio 60 GHz wide band signals which is even much more practical for ranging and localization systems due to high time and multipath resolution. Typically, the 60GHz accurate ranging estimation is very important. In order to improve the precision of the ranging, a new threshold selection algorithm using neural network (NN) is proposed which is based on a joint metric of the skewness, kurtosis and standard deviation after energy detector (ED). Simulation results are presented which show the proposed NN algorithm provides better precision and robustness in both high and low SNR environments than other ED-based algorithms in the IEEE 802.15.3c channel models.

This investigation deals with single server queueing system wherein the arrival of the units follow Poisson process with varying arrival rates in different states and the service time of the units is arbitrary (general) distributed. The server may take a vacation of a fixed duration or may continue to be available in the system for next service. Using the probability argument, we construct the ...

In this paper, we propose and implement a novel IDbased secure ranging protocol. Our protocol is inspired by existing authenticated ranging and distance–bounding protocols, and is tailored to work on existing Ultra Wide Band (UWB) ranging platforms. Building on the implementation of secure ranging, we further implement a secure localization protocol that enables the computation of a correct dev...
متن کاملSecure Ranging With Message Temporal Integrity
In this paper, we address the problem of delay attacks on radio frequency time of arrival (ToA) secure ranging. In secure ranging, two mutually trusted devices try to determine their distance in the presence of an attacker. A delay attack consists of delaying the ranging messages exchanged between the devices, resulting in an increase of the measured message arrival times and thus in an increas...
