Optimal Clock Synchronization Under Energy Constraints in Wireless Ad-Hoc Networks
نویسندگان
چکیده
Clock synchronization is a crucial service in many distributed systems, including wireless ad-hoc networks. This paper studies external clock synchronization, in which nodes should bring their clocks close to the value of some external reference time, which is provided in the system by one or more source clocks. Reference broadcast synchronization (RBS) is a known approach that exploits the broadcast nature of wireless networks for a single hop. However, when networks are large in physical extent, additional mechanisms

LEBRP - A Lightweight and Energy Balancing Routing Protocol for Energy-Constrained Wireless Ad Hoc Networks
A wireless ad hoc network typically refers to any set of wireless networks where all devices have equal status on a network and are free to associate with any other wireless ad hoc network devices in their range. As the nature of these networks, they commonly do not have external power supplies, and each node has a limited internal power source. In this paper, we put forward a new routing proto...

Abstract Ad hoc Wireless Networks, are networks formed by a collection of nodes through radio. In wireless networking environment, formidable challenges are presented. One important challenge is connection maintenance mechanism for power consumption. In this paper, a multi-objective optimal design is considered for ad-hoc networks which address the electrical power of nodes effects on cross-l...
متن کاملInterval based time synchronization for mobile ad hoc networks
In this thesis, we make a case for the use of guaranteed intervals for time synchronization in mobile ad-hoc networks. In particular, we look at wireless sensor networks (WSNs), a specific class of mobile ad-hoc networks. WSNs are envisioned to comprise a large number of small, inexpensive devices that operate on a very constrained energy budget. Time synchronization is an important service in ...
متن کاملEvaluation of a BIBD Based Directional MAC Protocol for Wireless Ad Hoc Networks
The use of directional antennas in wireless ad hoc networks can significantly improve global performance due to a high spatial channel reuse. Nevertheless, its introduction poses new location dependent problems related to the MAC protocol. In this paper, the Balanced Incomplete Block Design theory has been exploited to develop a new MAC protocol for wireless ad hoc networks using directional ant...
متن کاملFast, Bio-Inspired Synchronization of Periodic Events
The synchronization of periodic events is an important and useful primitive for many aspects of ad-hoc wireless sensor networks (WSNs). Achieving and maintaining this, however, is difficult due to the limited energy sources, imprecise clocks, and high failure rates that plague WSNs. A firefly synchronization model by Mirollo and Strogatz [9] has inspired several self-organizing synchronization ...
