Logically-Centralized SDN-Based NDN Strategies for Wireless Mesh Smart-City Networks

The Internet of Things (IoT) is a key technology for smart community networks, such as smart-city environments, and its evolution calls stringent performance requirements (e.g., low delay) to support efficient communication among wide range objects, including people, sensors, vehicles, etc. At the same time, these ecosystems usually adopt wireless mesh extend their in large-scale IoT deployments. However, due high coverage, WMNs may face different network challenges according characteristic, example, (i) areas that include significant number nodes or (ii) with frequent dynamic changes link failures unstable topologies. Named-Data Networking (NDN) can enhance meet requirements, thanks content naming scheme in-network caching, but it necessitates adaptability challenging conditions WMNs. In this work, we aim at end-to-end NDN terms (i.e., delay), performing extended experimentation over real WMN, evaluating discussing benefits provided by two SDN-based strategies: (1) solution integrates operation routing decisions WMN protocol; (2) static one which based on clustering measurements.
