Performance Analysis of Time Synchronization Protocols on Different Commercial Mote Platforms
Neha Fotedar, Poonam Saini · Procedia Computer Science · 2018
Wireless sensor networks (WSNs) have astounding advantages for monitoring environmental properties and object movement. The small size of sensors in a WSN is used very craftily and is ideal for obscured observations. However, for these observations, the sensor clocks should be synchronized within a few microseconds of each other to accurately determine the point of origin. This paper shows the performance analysis of different time synchronization protocols over different mote platforms. Time synchronization protocols like Reference Broadcast Synchronization (RBS), Timing-Sync Protocol for Sensor Networks (TPSN), Hybrid Energy-Aware protocol and Minimum Distance Clustering Hybrid Synchronization (MDCHS) protocol are simulated over different mote platforms viz., MICA2Dot433, MICA2Dot916, MICAz and TelosB. Different performance metrics like Energy Usage and Synchronization Time are used to analyse the performance of these protocols. The model is simulated using MATLAB. The effects of changes in network topology and node density are also studied.
