Experimental investigation and analysis of clock model and sensor networks agents time synchronization

Abstract

Time synchronization is a critical and vital piece of infrastructure for any distributed system or sensor network design or real time simulation. Sensor network have many of the same requirements as traditional distributed systems. Distributed wireless sensor networks make extensive use of synchronized time stamps in swarm navigation. Our target is to investigate the time synchronization in the network agents and determine the parameters of individual clock elements of the network. Therefore this paper shows design of clock model, time stamp exchange principle and linear regression for clock time update. It is found from the real-time simulation that the mean of error Probability Distribution Function (PDF) is 20 ms with maximum error probability 2.2% for free running oscillator. The outlayers were removed, and the error was minimized by linear regression method.
