Vehicular Ad-Hoc Networks (VANET) generalization of Mobile Ad Hoc Networks (MANET) are proclaimed for extreme mobility as compared to MANET. Motivation of VANET is Traffic Administration and Human Protection. Misuse of utilities provided by VANET is more prone to attacks like Black Hole Attack and Sybil Attack. This paper is fascinated towards recognition and eviction of Sybil Attack in VANET. ...

lack of infrastructure in ad hoc networks makes their deployment easier. Each node in an ad hoc network can route data using a routing protocol, which decreases the level of security. Ad hoc networks are exposed to several attacks such as the blackhole attack. In this article, a study has been made on the impact of the attack on the hybrid routing protocol ZRP (Zone Routing Protocol). In this a...

Mobile ad hoc networks (MANETs) are a set of mobile nodes which over a shared wireless medium communicate with each other without the presence of a predefined infrastructure or a central authority. [1]. The absence of a central management agency or a fixed infrastructure is a key feature of MANETs. Security issues in MANET are a challenging task nowadays. MANETs are vulnerable to passive attack...

Mobile Ad Hoc Networks (MANETs) is a collection of wireless mobile nodes connected by wireless links forming a temporary network without the aid of any infrastructure or any centralized administration. Owing to its mobility and broadcast nature MANETs are particularly vulnerable to attacks over traditional wired networks finally makes them susceptible to various active and passive attacks. In p...

The Optimized Link State Routing Protocol is developed for Mobile Ad Hoc Network. It operates as a table driven, proactive protocol. The core of the OLSR protocol is the selection of Multipoint Relays (MPRs), used as a flooding mechanism for distributing control traffic messages in the network, and reducing the redundancy in the flooding process. A node in an OLSR network selects its MPR set so...

astrophysics is becoming now an integral part of general physics. considering the black hole theory ,which is a new and exciting branch of relativistic astrophysics, we see many connections between elementary particle physics and astrophysics. in this article we attempt to explain the development of star physics ,in an easy ,understandable manner. previous knowledge of relativistic theory or cl...

ABSTRACT Recently, Wireless ad hoc networks became a hot research topic among researchers due to their flexibility and independence of network infrastructures, such as base stations. Network Early work in MANET research has mainly focused on developing an efficient routing mechanism in such a highly dynamic and resourceconstrained network. At present, several efficient routing protocols have be...

In the past few years, an evolution in the wireless communication has been emerged, along with the evolution a new type of large potential application of wireless network appears, which is the Mobile Ad-Hoc Network (MANET). Black hole attack considers one of the most affected kind on MANET. Therefore, the use of intrusion detection system (IDS) has a major importance in the MANET protection. In...

A mobile adhoc network (MANET) is an infrastructure-less type network, which consists of number of mobile nodes with wireless network interfaces. In MANET every node can functions as transmitter, router and data sink. MANET has dynamic topology which allows nodes to join and leave the network at any point of time. MANET is more vulnerable due to its characteristics such as dynamic topology, dis...

Seas and oceans are the most important sources of renewable energy in the world. The main purpose of this paper is to use an appropriate control strategy to improve the performance of point absorbers. In this scheme, considering the high uncertainty in the parameters of the power take-off system in different atmospheric conditions, a new improved black hole algorithm is introduced to tune fuzzy...
