Smart communications via a tree-based overlay over multiple and heterogeneous (TOMH) spontaneous networks

Abstract

Abstract-The current networking scenario is characterized by widespread availability of ubiquitous devices with significant processing capabilities, e.g., smartphones, tablets, and laptops. In addition, the simultaneous availability of multiple connectivity interfaces, e.g., cellular, WiFi, and Ethernet, pushes towards spontaneous networking scenarios where devices create a multinetwork environment based on collaborative and best-effort dispatching of packets. Connectivity in such novel scenarios is far less reliable than in traditional networks, e.g., links abruptly dis/appear simply due to node mobility, thus making hard to support quality-sensitive applications. In this paper, we present our framework for Tree-based Overlay over Multiple and Heterogeneous (TOMH) spontaneous networks for easily supporting smart network management features on top of heterogeneous multi-network environments. TOMH creates and maintains a dynamic and mobility-aware tree-based overlay network to integrate different connectivity technologies while enabling a tradeoff between accuracy of the global network view and collection/monitoring overhead. The TOMH overlay construction mechanism has been thoroughly validated and evaluated via simulation studies: the reported experimental results reveal that our proposal significantly outperforms comparable solutions for MANET environments, especially when the size of the targeted multi-network increases.

A Reference Model and Prototype Implementation for SDN-Based Multi Layer Routing in Fog Environments

“…Moreover, in the tested environments, devices and services are discovered via a basic controlled-flood approach, thus dispatching discovery messages along every available path (but avoiding loops by dropping duplicated messages). In case of more articulated topologies, scalability can be increased by adopting a tree-based control packet dispatching schema, e.g., the one presented in [10].…”

SDN-Based Traffic Management Middleware for Spontaneous WMNs

“…In this manner we can ensure reduced latency even in the challenging case of control and data plane messages sharing and competing for the same networking resources (of course, better performance can be achieved in the simpler scenarios with control and data plane exploiting different networks and thus not interfering one another). In addition, scalability can be further increased by adopting a tree-based control packet dispatching schema, e.g., the one presented in [39].…”

MINA: A reflective middleware for managing dynamic multinetwork environments

“…This requires a model that can estimate the current path duration and next path available time, according to mobility model, nodes density, and traffic pattern. More details can be found in [14], [15].…”

“…The MINA client is also being currently ported to Android and MacOS platforms. On the client side, MINA extends the RAMP middleware (for dynamic sharing of resources available via heterogeneous links [4] [20]) to support the MINA tiered architecture and the client-server paradigm (additional information can be found in [15]). …”

“…There are three types of links in this network with data rates of 100Mbps, 10Mbps and 2Mbps. Due to space limitations, we focus on results from the Analyze and Adapt steps -and assume that the network state information captured in the Observe step is already in the database (more details in [15]). In particular, our experiments aim to explore how formal methods based approaches within the OAA loop can help in improving performance via adaptive route planning for multiple flows.…”
