Trade-offs between latency, complexity, and load balancing with multicast algorithms [PDF]
, 2010 The increasing number of collective communication-based services with a mass interest and the parallel increasing demand for service quality are paving the way toward end-to-end QoS guarantees.

Trust based secure routing algorithm for wireless sensor networks
Tongxin xuebao, 2008 In order to deal with the safety hidden trouble caused by that the nodes in wireless sensor networks were lack of fixed infrastructure and it was hard to check the malicious behavior of the nodes, so the conception of nodes’ trust was proposed combined ...

A Secure Localization Approach against Wormhole Attacks Using Distance Consistency
EURASIP Journal on Wireless Communications and Networking, 2010 Wormhole attacks can negatively affect the localization in wireless sensor networks. A typical wormhole attack can be launched by two colluding attackers, one of which sniffs packets at one point in the network and tunnels them through a wired or ...

Hyperbolic Casimir-like wormhole
European Physical Journal C: Particles and FieldsWe present a systematic study of exact solutions for traversable wormhole geometries in a static and hyperbolic symmetric spacetime. In the conventional form of studying wormhole geometry, traversability requires the presence of exotic matter, which also

Quantum detection of wormholes [PDF]
Scientific Reports, 2017 AbstractWe show how to use quantum metrology to detect a wormhole. A coherent state of the electromagnetic field experiences a phase shift with a slight dependence on the throat radius of a possible distant wormhole. We show that this tiny correction is, in principle, detectable by homodyne measurements after long propagation lengths for a wide range ...

Ricci inverse gravity wormholes
Physics Letters BThe current study deals with the new wormhole solutions in the background of fourth order new modified Ricci inverse gravity. Two new classes of the wormhole solutions are analyzed by showing the valid region for the main part of wormhole geometry under ...

Existence of vacuum wormholes in Einsteinian cubic gravity
Journal of High Energy PhysicsWormhole solutions in gravitational theories typically require exotic matter. Here we present a wormhole solution to the field equations of Einsteinian Cubic Gravity — a phenomenological competitor to general relativity that includes terms cubic in the ...

Journal of High Energy PhysicsAfter averaging over fermion couplings, SYK has a collective field description that sometimes has “wormhole” solutions. We study the fate of these wormholes when the couplings are fixed. Working mainly in a simple model, we find that the wormhole saddles
