Optimized Time Synchronization Algorithm Inspired By Nature

The effect of time synchronization within the sensor nodes in Wireless Sensor Networks is an ongoing research area. It has received a huge amount of attention in the last decade. This paper discusses nature inspired algorithm, Ant Colony Optimization based Time-Sync(ACOTS) algorithm to provide an energy optimized solution to resolve time synchronization in WSN. Ant Colony optimization algorithm is implemented, and it was observed that it drastically reduces the number of packets transmitted and received during the synchronization process. This would help to solve time synchronization problem as well as it will also create an energy efficient network. The proposed algorithm ACOTS is compared with the already existing algorithms for e.g. Reference-Broadcast Synchronization (RBS) and Time-Sync Protocol for Sensor Network (TPSN). Comparative results suggested ACOTS uses less exchange of messages than other schemes.
