Mobile adhoc network (MANET) is a collection of wireless nodes that dynamically create a wireless network among them without using any infrastructure. Nodes are free to move, independent of each other which makes routing much difficult. The routing protocols in MANET should be more dynamic so that they quickly respond to topological changes. On-Demand(More)
Mobile ad hoc network is a collection of mobile nodes which are dynamically and arbitrarily located in such a manner that the interconnections between nodes are capable of changing on a continual basis. In order to facilitate communication within the network, a routing protocol is used to discover routes between nodes. This paper examined routing protocols(More)
The Internet and recent global cyber terrorism have fundamentally changed the way organizations approach security. Recent worm and virus incidents such as Code Red, Nimda, and the Slammer worm have heightened security awareness. Also, numerous other threats have emerged recently that are particularly troublesome. Hence some solution must be provided to(More)
In this paper, we use three traffic generators namely exponential, Pareto and CBR (Constant Bit Rate) over an ad hoc network and analyze the behavior of routing protocols. Moreover, we take two parameters offered load and packet size which are important to determine the nature of ad hoc network routing protocols in the different traffic patterns. Further,(More)
In the present investigation, effects of ethanolic extract of Nigella sativa seed extract on insulin resistant non insulin dependent diabetic (NIDDM) guinea pigs were studied. Significant (p<0.05) decrease in blood glucose level and glycosylated haemoglobin were observed in animals treated with ethanolic extract of N. sativa. In addition, improvement in(More)
Security is a crucial service in wireless sensor networks that is becoming increasingly common in WSNs because wireless sensor nodes are typically deployed in an unattended environment, leaving them open to possible hostile network attack. Because wireless sensor nodes are limited in computing power, data storage and communication capabilities, any user(More)
MANETs suffer from performance and security issues. Many contributions have been proposed but they are not sufficient to enhance the security and performance. Therefore the presented paper investigate techniques of wormhole attack deployment over wireless ad hoc network, and efforts made to avoid these attack . Finally a new IDS is presented for securing(More)
Introduction: Adverse effects of herbal products have often been ignored apparently due to its common use and acceptance over allopathic. Diverse studies on the medicinal properties of Nigella sativa are easily accessible, nevertheless, very few concerns for its toxicity. Objective: The present study was designed to evaluate cytotoxicity of ethanolic(More)
