On The Multi-Hop Extension of Energy-Efficient WSN Time Synchronization Based on Time-Translating Gateways
Qimeng Liao, Kyeong Soo Kim
We report preliminary results of a simulation study on the multi-hop extension of the recently-proposed energy-efficient wireless sensor network time synchronization scheme based o…
Simulation Study of an Energy-Efficient Time Synchronization Scheme based on Source Clock Frequency Recovery in Asymmetric Wireless Sensor Networks
Kyeong Soo Kim, Sanghyuk Lee, Eng Gee Lim
In this paper we report preliminary results of a simulation study on an energy-efficient time synchronization scheme based on source clock frequency recovery (SCFR) at sensor nodes…
Energy-Efficient Time Synchronization Based on Asynchronous Source Clock Frequency Recovery and Reverse Two-Way Message Exchanges in Wireless Sensor Networks
Kyeong Soo Kim, Sanghyuk Lee, Eng Gee Lim
We consider energy-efficient time synchronization in a wireless sensor network where a head node (i.e., a gateway between wired and wireless networks and a center of data fusion) i…
Comments on "On Clock Synchronization Algorithms for Wireless Sensor Networks Under Unknown Delay"
Kyeong Soo Kim
The generalization of the maximum-likelihood-like estimator for clock skew by Leng and Wu in the above paper is erroneous because the correlation of the noise components in the mod…
