ion Abstraction is a common approach to improving simulator performance. All simulators adopt some level of abstraction when choosing what to simulate. FlowSim was the first network simulator to make this trade-off explicit.7 Ns supports several levels of abstraction. Numerous simulation interfaces are possible, including programming in a high-level scripting language, a more traditional system...

Several routing protocols for mobile ad hoc networks work efficiently only in bidirectional networks. Unidirectional links may exist in a real network due to variation in transmission power of different nodes, noise or other signal propagation phenomena, and heterogeneity in transmission hardware of nodes in the network. We introduce a sub-layer called Sub Routing Layer, SRL, between the networ...

This paper proposes XML-Defined Network policies (XDNP) a new high level language based on XML notation to describe network control rules in Software Defined Network environments. We rely on existing OpenFlow controllers specifically Floodlight but the novelty of this project is to separate complicated languageand framework-specific APIs from policy descriptions. This separation makes it possib...

Active networks provide the possibility to perform computations within the network. This feature introduces greater flexibility, but more complexity as well. Therefore, a sound management of active networks is a prerequisite to the acceptance of such networks. Management of large complex systems can be improved with the introduction of further abstraction levels and with moving the responsibili...

Maximizing product adoption within a customer social network under a constrained advertising budget is an important special case of the general influence maximization problem. Specialized optimization techniques that account for product correlations and community effects can outperform network-based techniques that do not model interactions that arise from marketing multiple products to the sam...

We introduce the design and deployment of the latest version of the VNode infrastructure, VNode-i. We present new extended VNode-i functions that offer high performance and provide convenient deep programmability to network developers. We extend resource abstraction to the transport network and achieve highly precise slice measurement for resource elasticity. We achieve precise resource isolati...

Dynamic group formation and discovery is an important component of several emerging end system applications and network services including peer-to-peer and overlay systems, network storage/caching systems, and reliable multicast/distribution services. In our previous work, we proposed a programmable, scalable grouping service based on multicast and concast. In this paper, we present a generaliz...
