The idea that electromagnetic charge may be a manifestation of the topology of space has a very long history [Whe, WM, Sor]. The basic configuration considered by Wheeler and Misner was a space that contained a handle-like region, often called a wormhole. This space is traversed by sourceless electric lines of force that enter the wormhole radially through one mouth and exit through the other o...

We present a new analytical approach for the performance evaluation of asynchronous wormhole routing in k-ary n-cubes. Through the analysis of network flows, our methodology furnishes a closed formula for the average message delay in wormhole deterministic routing. In this paper, the focus is on 30 asymmetric torus networks with uni-directional or bi-directional links. However, the model can be...

We construct regular multi-wormhole solutions to a gravitating σ model in three space-time dimensions, and extend these solutions to cylindrical traversable wormholes in four and five dimensions. We then discuss the possibility of identifying wormhole mouths in pairs to give rise to Wheeler wormholes. Such an identification is consistent with the original field equations only in the absence of ...

Wireless sensor networks can be deployed in inhospitable terrains or in hostile environments to provide continuous monitoring and processing capabilities. Due to the wireless and distributed nature, security is very crucial issue in wireless sensor network. Security comes from attacks. Detecting wormhole attack is very hard compared to other attacks because it uses private, out-of-band channel ...

In this paper, we propose a real-time communication scheme that can be used in general point-to-point real-time multicomputer systems with wormhole switching. Real-time communication should satisfy the two requirements of predictability and priority handling. Since traditional wormhole switching does not support priority handling, which is essential in real-time computing, flit-level preemption...

Quite exotic relativistic objects known as wormholes are hypothetical candidates for central machine of active galactic nuclei as well as black holes. We find the magnitude of the perihelion precession and the deflection of light in gravitational field of a wormhole and compare them with those for a black hole. The impact parameter is taken to be much larger than the wormhole throat size. We sh...

Mobile ad hoc network (MANET) is vulnerable to many types of routing attacks due to its dynamic topology and the collaboration of MANET nodes in finding routing paths. The wormhole attack is considered one of the most threatening attacks. The most popular MANET routing protocols such as ad hoc on demand distance victor (AODV) are vulnerable to this security threat. In this paper, a lightweight ...

EEcient routing of messages is the key to the performance of multicomputers. Mul-ticast communication refers to the delivery of the same message from a source node to an arbitrary number of destination nodes. Wormhole routing is the most promising switching technique used in new generation multicomputers. In this paper, we present multicast wormhole routing methods for multicomputers adopting 2...

ATM has been adopted as the main high speed technology in both wide and local area networks. When ATM is combined with credits −the flow control mechanism that is particularly suitable for local data communication− it becomes appropriate for multiprocessor interconnection networks as well. Actually, credit-flowcontrolled ATM has similarities with wormhole routing, one of the most popular archit...

A router design for torus networks that significantly reduces message latency over traditional wormhole routers is presented in this paper. This new router implements virtual cut-through switching and fully-adaptive minimal routing. Packet deadlock is avoided by providing escape ways governed by Bubble flow control, a mechanism that guarantees enough free buffer space in the network to allow co...
