Managing large IP networks requires an understanding of the current traac ows, routing policies, and network connguration. Yet, the state-of-the-art for managing IP networks involves manual connguration of each IP router, and traac engineering based on limited measurements. The networking industry is sorely lacking in software systems that a large Internet Service Provider (ISP) can use to supp...

Sharing musical files via the Internet was the essential motivation of early P2P systems. Despite of the great success of the P2P file sharing systems, these systems support only "simple" queries. The focus in such systems is how to carry out an efficient query routing in order to find the nodes storing a desired file. Recently, several research works have been made to extend P2P systems to be ...

in mobile ad hoc networks, the absence ofinfrastructure and the consequent absence of authorizationfacilities impede the usual practice of establishing a practicalcriterion to distinguishing nodes as trusted and distrusted.since all nodes in the manets would be used as router inmulti-hop applications, secure routing protocols have vital rulein the security of the network. so evaluating the perf...

We consider the problem of designing an overlay network and routing mechanism that permits finding resources efficiently in a peer-to-peer system. We argue that many existing approaches to this problem can be modeled as the construction of a random graph embedded in a metric space whose points represent resource identifiers, where the probability of a connection between two nodes depends only o...

The Internet is far from achieving the “five 9s” (99.999%) of availability provided by the public telephone network. Based on anecdotal evidence as well as a first-of-its-kind measurement study assessing routing failures affecting Amazon’s EC2 data centers, we find that network outages are surprisingly common and highly problematic. These outages incur large costs, disrupt critical services and...

in this study the location routing problem with fuzzy parameters is taken into account, this problem involves determining the location of the depots and routing of the vehicles in order to serve the customers. in this study a location routing problem with fuzzy travel times and due dates is considered and two objective models are proposed. the considered objectives are minimizing the total cost...

Abstract- Efficient message delivery in city environment is required to ensure driver’s safety and passenger’s comfortability. In cities of developed nations, routing of data in vehicular Ad hoc Network (VANET) faces many challenges such as radio obstacles, mobility constraints and uneven nodes distribution. These factors primarily makes communication between vehicles complex. To overcome and t...
