As compared to traditional distributed computing paradigms, a major advantage of the cloud computing is the ability to provide more reliable, affordable and flexible resources for the applications (or users). The need to manage the applications in the cloud computing creates the challenge of an on-demand resource provisioning and allotment in response to the dynamically changing workloads. Currently,...
The Cloud Computing environment provisions the supply of computing resources on the basis of demand, as and when needed. It builds upon the advances of virtualization and distributed computing to support the cost efficient usage of computing resources, emphasizing on the resource scalability and on-demand services. It allows business outcomes to scale up and down their resources based on the needs...
For the mobile ad hoc networks (MANET) security is a vital element. For providing security against malicious nodes all the researchers are striving specially and particularly on all the security challenges in the MANETs. Within these wirelessnetworks some special techniques have been propounded for secure routing protocols. Our propounded work presents a more effective outcome to mitigate black hole...
A Mobile Ad-hoc Network (MANET) covers a set of autonomous mobile nodes that communicates through the wireless communication in an infrastructure-less environment. Mostly, MANETs are used in group communication mechanisms like military applications, rescue operations, emergency search, vehicular ad-hoc communications and mining operations etc. In such type of networks, a group communication takes...
Mobile ad-hoc network (MANET) is decentralized network, in this network nodes can move dynamically. OSI Network layer faces several attacks. Black hole attack work on highest sequence number during Replay message, a group of black hole nodes easily employed against routing in MANET called collaborative black hole attacks. When two malicious nodes cooperatively create a tunnel thereby formed worm hole...
