This paper presents a pattern recognition-based scheme for detection of islanding conditions in synchronous- based distributed generation (DG) systems. The main idea behind the proposed scheme is the use of spatial features of system parameters such as the frequency, magnitude of positive sequence voltage, etc. In this study, the system parameters sampled at the point of common coupling (PCC) w...

This paper proposes a novel concept of multidestination message passing mechanism for wormhole k-ary n-cube networks. Similar to the familiar car-pool concept, this mechanism allows data to be delivered to or picked-up from multiple nodes with a single message-passing step. Such messages can propagate along any valid path in a wormhole network conforming to the underlying base routing scheme (d...

The wireless networks are more sensitive to the Denial-of-Service (DoS) attacks. The existing system is based on Spread Spectrum (SS). This technique mainly focuses on an external threat model. In wireless network the communications between nodes take place through broadcast communication. That is why, if an attacker present within the network can easily eavesdrop the message sent by any node. ...

Based on the production data and statistical information of a practical oilfield, it is proved that the flow rule in wormhole or extra wormhole can be regarded as a high speed Non-Darcy flow, and used the Forchheimer equation to represent. The Forchheimer model is superior to the exponent model and Mazaheri model. Then, the productivity equation of poorly consolidated reservoir with wormhole is...

Vehicular Ad hoc Networks (VANET) is the subclass of Mobile Ad Hoc Networks (MANETs). It is the most advanced technology that provides Intelligent Transportation System (ITS) in wireless communication among vehicles to vehicles and road side equipment (RSUs) to vehicles according to IEEE 802.11p standard. VANET provides broad range of safety and non safety applications. Safety application provi...

We have investigated the gravitational lensing by two wormholes, viz., Janis Newman-Winnicour (JNW) wormhole and Ellis wormhole. The deflection angle in the strong field limit is calculated and various lens parameters of two wormholes are compared. It is shown that the JNW wormhole exhibits the relativistic images, while the Ellis wormhole does not have any relativistic images due to the absenc...

Many errors in data communication cause security attacks Internet of Things (IoT). Routing at network layer are prominent IoT which degrade the quality communication. like sinkhole attack, blackhole selective forwarding attack and wormhole enter through IoT. This paper has an emphasis on detection a because it is one most uncompromising protocol stack. The disruptive out all other mentioned abo...

Wireless Sensor Networks refers to a multi-hop packet based network that contains a set of mobile sensor nodes. Every node is free to travel separately on any route and can modify its links to other nodes. Therefore, the network is self organizing and adaptive networks which repeatedly changes its topology. The relations among nodes are restricted to their communication range, and teamwork with...

Space-time wormholes were introduced in Wheeler’s idea of space-time foam. Traversible wormholes as defined by Morris & Thorne became popular as potential short cuts across the universe and even time machines. More recently, the author proposed a general theory of wormhole dynamics, unified with black-hole dynamics. This article gives a brief review of the above ideas and summarizes progress on...
