Mobile Ad-hoc Networks (MANET) are decentralized wireless networks that communicate without pre-existing infrastructure. MANETs vulnerable to the most popular types of attacks and threats, such as wormhole attacks. A is very challenging issues records packets from one location network tunnels them another undermines performance disrupt routing protocol. However, existing solutions have been dev...

We consider the use of wormhole routed networks as internal interconnects of switches. The interconnection of two wormhole networks that are free from deadlocks does not necessarily produce a deadlock free network. This is problematic when wormhole networks are used as switch-internal fabrics, because it severely restricts the possibilities for coupling the switches together. This paper present...

We present a traversable-wormhole solution of the gravitational field equation General Relativity without need exotic matter (exotic can, for example, have negative energy density and vanishing isotropic pressure). Instead matter, relies on 3-dimensional "spacetime defect" characterized by locally metric determinant.

The infrastructure of a Mobile Ad hoc Network (MANET) has no routers for routing, and all nodes must share the same routing protocol to assist each other when transmitting messages. However, almost all common routing protocols at present consider performance as first priority, and have little defense capability against the malicious nodes. Many researches have proposed various protocols of high...

For real-time communication, we must be able to guarantee timely delivery of messages. In recent years, improvements in technology have made possible switch-based local area networks (LANs) and system area networks (SANs) that use wormhole switching, a pipelined switching technique which permits significantly shorter network latencies and higher throughputs than traditional store-and-forward pa...

Christopher Nolan’s science fiction movie Interstellar offers a variety of opportunities for students in elementary courses on general relativity theory. This paper describes such opportunities, including: (i) At the motivational level, the manner in which elementary relativity concepts underlie the wormhole visualizations seen in the movie. (ii) At the briefest computational level, instructive...

In ad hoc networks, malicious nodes can carry wormhole attacks to fabricate a false scenario on neighbour relations among mobile nodes. The attacks threaten the safety of ad hoc routing protocols and some security enhancements. In the wormhole attack, an attacker records packets (or bits) at one location in the network, tunnels them (possibly selectively) to another location, and retransmits th...

As DV-Hop algorithm estimates distance by distance vector exchanging, positioning process is vulnerable to devastate wormhole attacking. An improved DV-Hop algorithm (AWADV-Hop) which resists wormhole attack is proposed, based on the original algorithm in this paper. To solve the problem that hops and the average distance per hop is the most vulnerable to wormhole attack in DV-Hop. This paper f...

During the dissolution of porous rock, positive feedback between fluid transport and mineral dissolution leads to the spontaneous formation of pronounced wormhole-like channels. In a recent paper, Cohen et al. (2008) analyzed wormhole growth and competition in a dissolving porous rock, using a Darcy-scale numerical model developed by Golfier et al. (2002). In particular, they analyzed the compe...
