Security Improved Mobi-Sync Protocol for Under Water Sensor Network
نویسندگان
چکیده
Time synchronization plays a critical role in distributed network systems. In this paper, we investigate the time synchronization problem in the context of underwater sensor networks (UWSNs). A synchronization algorithm for UWSNs must consider additional factors such as long propagation delays from the use of acoustic communication and sensor node mobility. These unique challenges make the accuracy of synchronization procedures for UWSNs even more. This paper modifies Mobi-Sync, a novel time synchronization scheme for mobile underwater sensor networks for developing secure time synchronization method. Mobi-Sync distinguishes itself from previous approaches for terrestrial WSN by considering spatial correlation among the mobility patterns of neighboring UWSNs nodes. Mobi-Sync outperforms existing schemes in both accuracy and energy efficiency, but mobi-Sync doesnt consider the security aspetcs.

متن کاملA Performance Comparison of Clock vs. Event Synchronization Protocols
Sensor network applications often need accurate temporal information on observations reported from distributed sensor nodes to correctly infer application semantics. Since the nodes’ local clocks can go out-of-sync due to clock drifts, a networked time synchronization protocol is needed to keep their clocks synchronized to a reference clock. In this paper, we provide a performance comparison be...
