Q(k) p(k) +-f(k) b 3 b 2 r(k-1) w 1 w 2 A new signaling system for high bit rate wireless LANs is made possible by a novel class of signaling pulses called OWSS pulses, which are generated through a combination of OWDM and spread spectrum concepts.

This contribution proposes for Recommendation G.812 (1) a holdover specification for Clock Type II that is consistent with the current specification of 10 per day and is not broken into aging, temperature, and initial offset components and (2) a modification to the output wander TDEV mask, to apply only to Types II and III, to make the mask consistent with the respective wander generation TDEV ...

Key management plays fundamental role in research on security service in wireless sensor networks (WSNs). However, due to the resource constraints, establishing pairwise keys in WSNs is not a trivial tasks. Several exiting key management schemes have been proposed in literature to establish pairwise keys between sensor nodes, but they either can not offer strong resilience against node capture ...

Non-repudiation is a security service that provides cryptographic evidence to support the settlement of disputes. In this paper, we introduce the state-of-the-art of non-repudiation protocols for multiple entities. We extend an existing multi-party non-repudiation (MPNR) protocol to allow an originator to send different messages to many recipients in a single transaction. We further propose an ...

In this paper, a new structure is provided for the dispersion compensating photonic crystal fibers in order to broaden the chromatic dispersion and increase the dispersion compensating capability in a wide wavelength range. In the structure, putting a combination of circular holes and a star structure in the inner core clad causes the dispersion coefficient profile to be broadened, and addition...

The massive introduction of technical advances in the Transport Network (Dense Wavelength Division Multiplexing, optical Crossconnects and Add Drop multiplexers), forced by bandwidth demand growth, creates new needs to manage it in an efficient and integrated way via a Common Control and Management Plane..The Generalized Multiprotocol Label Switching has been for several years the subject of IE...
