Journal ArticleDOI
Internet of things: Vision, applications and research challenges
TL;DR: A survey of technologies, applications and research challenges for Internetof-Things is presented, in which digital and physical entities can be linked by means of appropriate information and communication technologies to enable a whole new class of applications and services.
Journal ArticleDOI
Lightpath communications: an approach to high bandwidth optical WAN's
TL;DR: It is shown that although the problem of optimally establishing lightpaths is NP-complete, simple heuristics provide near optimal substitutes for several of the basic problems motivated by a lightpath-based architecture.
Journal ArticleDOI
Making transmission schedules immune to topology changes in multi-hop packet radio networks
Imrich Chlamtac,András Faragó +1 more
TL;DR: A robust scheduling protocol is proposed which is unique in providing a topology transparent solution to scheduled access in multi-hop mobile radio networks and is robust in the presence of mobile nodes.
Proceedings ArticleDOI
CogMesh: A Cluster-Based Cognitive Radio Network
TL;DR: This paper proposes a cluster-based framework to form a wireless mesh network in the context of open spectrum sharing and identifies issues in such a network and provides mechanisms for neighbor discovery, cluster formation, network formation, and network topology management.
Journal ArticleDOI
CORD: contention resolution by delay lines
Imrich Chlamtac,Andrea Fumagalli,Leonid G. Kazovsky,P. Melman,W. H. Nelson,Pierluigi Poggiolini,M. Cerisola,A. N. M. M. Choudhury,T.K. Fong,R.T. Hofmeister,C.L. Lu,A. Mekkittikul,IX D.J.M. Sabido,Chang-Jin Suh,Eric Wong +14 more
TL;DR: The consortium, funded by ARPA, has three main goals: investigating networking issues involved in optical contention resolution, constructing an experimental contention-resolution optical (CRO) device, and building a packet-switched optical network prototype employing a CRO and novel signaling/synchronization techniques.
