CoAP is a web transfer protocol that provides basic RESTful services for IoT devices. Since CoAP operates on top of UDP, CoAP must support additional congestion control and reliability mechanisms. However, CoAP is originally designed to allow implementations that do not maintain any end-to-end connection information. Thus, the default congestion control mechanisms are not capable of adapting to network...
Vehicular Delay Tolerant Networks (VDTNs) appears as an innovative approach to deal with several issues faced by vehicular communications. By exploiting vehicles and deploying a DTN store-carry-and-forward paradigm with an Internet protocol over VDTN it is possible to enable asynchronous communications in the absence of end-to-end links. VDTNs also combine a bundle-oriented communication with an out-of-band...
Software Defined Networking (SDN) and OpenFlow represent the most commonly deployed approaches of the so called Programmable Networks. SDN is an emerging network architecture, which performs the subdivision of control plane and data plane and allows greater speed, greater scalability, and greater ductility in terms of routing and forwarding. OpenFlow, instead, is an SDN component that characterizes...
