Ledeczi, "The flooding time synchronization
protocol", in Proc.
Traditional methods of time synchronization
in ordinary networks are not applicable in the sensor network since they are complex in nature and consume more power.
"Mobi-Sync: Efficient Time Synchronization
for Mobile Underwater Sensor Networks," IEEE Trans.
When reporting or forwarding data to the mobile sink, sensors calculate the location of the mobile sink based on a loose time synchronization
mechanism among sensor nodes and the mobile sink.
(i) SLSMP accomplishes time synchronization
and localization simultaneously and then it can be applied to many applications and other layers like MAC or network.
Distributed time synchronization
protocols which do not Require a hierarchal structure have been proposed in [3, 9, 10], where the authors have considered a continuous time system to represent the clock of a sensor node.
Zheng, "Finite time synchronization
between two different chaotic systems with uncertain parameters," Computer & Information Science, vol.
In this case it is important that there is some mechanism for distributing absolute time synchronization
signals to all monitoring points.
The recorders provide high quality images and feature a built-in network time protocol server to ensure automatic and reliable system time synchronization
. Other features include remote surveillance using a standard network browser, secure user access, and double keylock protection.
Features include Ethernet connectivity; a built-in secure web server; time synchronization
; data-logging of host messages, field unit commands, and status changes; and email notification of alarm conditions.
"Dell recognizes that the TymServe 2100 simplifies the task of implementing and maintaining a network time synchronization
system, offering better timing accuracy, decreasing security risk and providing a lower cost of ownership," commented Paul Skoog, product marketing manager at Symmetricom.
Still, time synchronization
problems are myriad, according to the report.
