Executive Summary

The present paper develops a decentralized inter-base station slot synchronization algorithm suitable for cellular mobile communication systems. The proposed Cellular Firefly Synchronization (CelFSync) algorithm is derived from the theory of pulse-coupled oscillators, common to describe synchronization phenomena in biological systems, such as the spontaneous synchronization of fireflies. In order to maintain synchronization among Base Stations (BSs), even when there is no direct link between adjacent BSs, some selected User Terminals (UTs) participate in the network synchronization process.
