Table 4.1 Relative clock drift rate based secure time synchronization. Relative Clock Drift Rate Based Secure Time Synchronization Protocol.

It is usually necessary to have a cluster of sensor nodes share a common view of a local clock time, so that all these nodes can coordinate in some important ...

This scheme is suitable for Wireless sensor networks (WSNs) with negligible encryption and decryption time. The second part is the process of calculating the ...

In this article, we analyze attacks on existing time synchronization protocols for wireless sensor networks and we propose a secure time synchronization toolbox ...

Mar 20, 2023 · If relative drift is 1 and relative offset is 0, then both clocks are perfectly synchronized. Clock rate of the network node and offset can be ...

Our approaches guar- antee that normal nodes can synchronize their clocks to the common source node even if each normal node has up to col- luding malicious ...

This paper reviews the existing clock synchronization protocols for WSNs and the methods of estimating clock offset and clock skew.

Besides, adjusting the local clock has better efficiency than maintaining relative clock since it requires more memory capacity and communication overheads [2].

The next method is relative timing in which the network clocks are independent of each other and the nodes keep track of drift and offset. Usually a node keeps ...

The paper studies different existing methods, protocols, significant time parameters (clock drift, clock speed, synchronization errors, and topologies) to ...
