An effective distributed synchronization method for device-to-device communications

Abstract

This paper configures an effective distributed synchronization architecture in a decentralized wireless network which are considered for device-to-device communication standards. The paper proposes a random transmit selection scheme with an adaptive selection factor, which works by allowing a node to choose randomly either transmitting or receiving the clock pulses. Each node updates its own clock time by using clock information from neighbors in a transmit mode, but not by all nodes. With the adaptive selection factor-based method, the proposed scheme achieves performance improvements in both convergence time and synchronization error senses. In all of the contexts, the proposed scheme suggests the simple but strongly effective architecture, and shows enhanced behaviors.
