7 tions are proposed for wormhole attacks in sensor networks, but only a few of 8 them take mobility of sensor nodes into account. We propose a distributed 9 wormhole detection scheme for mobile wireless sensor networks in which mobility 10 of sensor nodes is utilized to estimate two network features (i.e. network node 11 density, standard deviation in network node density) through using neighb...

A new solution has been presented for the spherically symmetric space time describing wormholes with Phantom Energy. The model suggests that the existence of wormhole is supported by arbitrarily small quantity of Phantom Energy. Wormholes are geometrical structures connecting two distinct space times. It is very interesting object in Modern science as because if traversable wormhole exists , th...

Preventing Collaborative Wormhole Attacks on AODV-Based Mobile Ad Hoc Networks c ©Vincent Koo, 2012 Master of Science Computer Science Ryerson University Due to recent advances in wireless communication technologies, mobile ad hoc networks (MANETs) have become the networks of choice for use in various applications. Unfortunately, this advantage comes with serious security concerns, particularly...

We derive an effective local operator produced by certain wormhole instantons in a theory containing a massless Wess-Zumino multiplet coupled to N=1 su-pergravity. The induced interactions are D terms, and hence will not lead to spontaneous supersymmetry breaking. We conclude that supersymmetry suppresses wormhole-induced matter couplings.

We have considered the possibility of a slowly rotating wormhole surrounded by a cloud of charged particles. Due to slow rotation of the wormhole, the charged particles are dragged, thereby producing an electromagnetic field. We have determined the strength of this electromagnetic field and the corresponding flux of radiation.

A temporary collection of wireless mobile nodes in decentralized manner is known as Mobile Ad hoc Network (MANET). In a hostile environment of MANET, security is the primary concern to achieve protected communication between mobile nodes. A number of nontrivial challenges to security designs mandate the demand of building multi-fence security solutions that achieve both extended protection and ...

The Internet is experiencing an evolution towards a ubiquitous network paradigm, via the so-called internet-of-things (IoT), where small wireless computing devices like sensors and actuators are integrated into daily activities. Simultaneously, infrastructure-less systems such as mobile ad hoc networks (MANET) are gaining popularity since they provide the possibility for devices in wireless sen...

We consider a scalar field with a negative kinetic term minimally coupled to gravity. We obtain an exact non-static spherically symmetric solution which describes a wormhole in cosmological setting. The wormhole is shown to connect two homogeneous spatially flat universes expanding with acceleration. Depending on the wormhole’s mass parameter m the acceleration can be constant (the de Sitter ca...

We present a model of performance bound calculus on feedforward networks where data packets are routed under wormhole routing discipline. We are interested in determining maximum end-to-end delays and backlogs of messages or packets going from a source node to a destination node, through a given virtual path in the network. Our objective here is to give a network calculus approach for calculati...
