MixedCache: Enabling Flow Directed Rule-Caching Scheme based on Heterogeneous Cache for OpenFlow

A novel key management scheme for heterogeneous sensor networks based on the position of nodes

Wireless sensor networks (WSNs) have many applications in the areas of commercial, military and environmental requirements. Regarding the deployment of low cost sensor nodes with restricted energy resources, these networks face a lot of security challenges. A basic approach for preparing a secure wireless communication in WSNs, is to propose an efficient cryptographic key management protocol be...

Simulation studies of OpenFlow-based in-network caching strategies

We propose an in-network caching architecture using OpenFlow to coordinate caching decisions in the network. Our scheme, called CacheFlow, extends the cache-and-forward concept by moving contents closer to the clients hop-by-hop using TCP for sending requests and retrieving contents. As such, CacheFlow can be incrementally implemented and deployed in the real network. In this paper, we present ...

Location-Based Caching Scheme for Mobile Clients

A High Level Rule-based Language for Openflow: A Proof of Concept based on Floodlight

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...

OpenQFlow: Scalable OpenFlow with Flow-Based QoS

OpenFlow, originally proposed for campus and enterprise network experimentation, has become a promising SDN architecture that is considered as a widely-deployable production network node recently. It is, in a consequence, pointed out that OpenFlow cannot scale and replace today’s versatile network devices due to its limited scalability and flexibility. In this paper, we propose OpenQFlow, a nov...
