Scalable and Passive Wireless Network Clock Synchronization in LOS Environments

Firefly Clock Synchronization in an 802.15.4 Wireless Network

This paper describes the design and implementation of a distributed self-stabilizing clock synchronization algorithm based on the biological example of Asian Fireflies. Huge swarms of these fireflies use the principle of pulse coupled oscillators in order to synchronously emit light flashes to attract mating partners. When applying this algorithm to real sensor networks, typically, nodes cannot...

Opportunistic Clock Synchronization in a Beacon Enabled Wireless Sensor Network

Wireless sensor networks (WSN) consisting of a large number of tiny inexpensive sensor nodes are a viable solution for many problems in the field of building automation. In order to meet the energy constraints, the nodes have to operate according to an extremely low duty cycle schedule. In such a scenario the reduction of the synchronization error, at least among directly communicating nodes, i...

Clock Synchronization for Wireless Networks

Time synchronization is a fundamental service in many wireless applications. While the synchronization problem is well-studied in traditional wired networks, physical constraints of the wireless medium impose a unique set of challenges. We present a novel time synchronization algorithm which is highly energy efficient and failure/recovery-tolerant. Our algorithm allows nodes to synchronize to s...
