Mobile ad-hoc network networks are self organizing, very dynamic network which support data networking without an infrastructure. The proposed protocol provides secure and adaptive backup routing protocol for MANET. Genetic algorithm (GA) is used to find the optimal path from the available multiple paths between source and destination to be used in the case of link

anytime, anywhere, and the need to rapidly introduce new revenue generating services is driving service providers to carefully scrutinize future network capital expenditures (CapEx). At the same time, network infrastructure energy costs are spiraling higher and driving up operational expenditures (OpEx). Faced with increasing CapEx and OpEx, service providers are looking for telecom and network...

Mobile Ad-hoc networks (MANET) is a collection of wireless mobile nodes forming a temporary network without using any centralized access point, infrastructure, or centralized administration. Till now wireless networking community designed hundreds of new routing protocols targeting the various scenarios of this design space. The paper present taxonomy of the mobile ad-hoc routing protocols and ...

Mobile end-systems frequently change their point of attachment to the network. In such an environment, in order for mobile devices to run without disruption, an inter-networking infrastructure is needed. In addition, a common networking protocol is required which can support network-wide mobility. Mobile devices also need to communicate with the existing pool of information servers and le serve...

Active networking is an expanding field of research. It includes the ability to easily install and modify customized network services and to process packets within the network in a customized way. This paper addresses the question of how the benefits of active networking can be exploited in an environment, where a large number of customers must share a common network infrastructure. We introduc...

Telecommunication service providers have begun to offer ubiquitous access to data. As a result, the Internet is not limited to computers that are physically connected but is also available to users that are equipped with mobile devices. This access fuels the growth and the usage of dynamic Internet, which needs increasing support for Internet Protocols and transmission control protocols over wi...

Denial of Service attacks are frequently presenting an increasing threat to the global inter-networking infrastructure in networking area . The algorithm for TCP congestion control algorithm is highly efficient for the various networking areas and operations as well its internal assumption of end-system cooperation results are well prone to attack by high-rate flows. A Shrew attack uses the con...

Optical networking technologies have been over the last two decades reshaping the entire telecom infrastructure networks around the world. As network bandwidth requirements increase, optical communication and networking technologies have been moving from their telecom origin into the enterprise. For example, today in data centers, all storage area networking is based on fiber interconnects with...

OpenFlow is a protocol-implementing Software Defined Networking, a new networking paradigm, which segregates packet forwarding and accounting from the routing decisions and advanced protocols. This segregation increases agility and flexibility and reduces operational expenses of the networking infrastructure. Despite the apparent benefits, many companies are unable to upgrade their networks to ...

In this paper, we propose a laboratory-based computer networking course to better teach various networking concepts to undergraduate students. Specifically, we ask students to build the lab network as a miniature Internet (MINT) from the ground up. Each laboratory builds upon the last until the desired infrastructure is in place. Students are then asked to set up common network services, extend...
