The Cloud-of-Chips (CoC) is a scalable MPSoC architecture comprised of a large number of interconnected Integrated Circuits (IC) and Processing Clusters (PC) destined for critical systems. While many researches have focused on addressing the hardware issues of MPSoCs, the communication over them has not been very well explored. Following the SDN concept, we propose a new protocol in order to secure the communication and efficiently manage the routing within the CoC. The SSPSoC includes a private key derivation phase, a group key agreement (GKA) phase, and a data exchange phase in order to ensure that basic security primitives are preserved and provide secure communication. Furthermore, a network of 1-30 nodes is set in order to validate the proposed protocol and measure the network performance and memory consumption of the proposed protocol.

This protocol focuses on Energy Efficiency and it is based on an existent open source protocol stack. RF-Tania protocol is an Ad-Hoc On Demand Protocol (Tania-AHOD). RF-Tania protocol is used on specific system architecture of a crowded sensors network. Such network is composed of two different types of equipment: The measuring sensor transponders and the Ad-hoc receivers. Sensor transponders are battery operated systems with installed sensors. Ad-hoc receivers are mobile phones equipped with transponders that operate as both sensor output devices as well as sensor data re-transmitters. In the case study, a test bed system architecture for monitoring CO2 and temperature levels has been used. In this study, tests of energy endurance, RF coverage and energy performance have been performed.

Hence a chiplet-based design has been initiated and quickly gain attention from industry, academia and government agencies. This cutting edge approach became advantageous to break down a large die into smaller chiplets in order to improve yield and binning. In order to exploit this new approach the interconnect fabric connecting the nodes of the entire system should be of high importance to enable the properly distribution of the data. Each individual chiplet may contain its own local Network on Chip (NoC), which operates for intra-chiplet traffic. However the communication over chiplet-based systems is complicated enough, due to various routing algorithms and NoC topologies and an alternative solution is needed. In this paper we introduce an SDNoC(Software Define Network on Chip)-based communication protocol for chiplet-based systems, called MicroLET, which consists of a flexible and modular SDNoC architecture and 3 main phases: Handshake, Network Monitoring, Routing. An implementation of the SDNoC architecture and an evaluation of the proposed routing algorithm compared to the XY and the Odd-Even algorithms within different traffic scenarios is presented. Through the evaluation of the MicroLET protocol, it is proven that it could be a good candidate for the future chiplet-based systems.

Therefore, in this paper we propose a flexible, technology-aware SoC design, named as Cloud-of-Chips (CoC), which is able to change its characteristics, such as routing logic, transmission paths, priorities, IC clustering, etc. We focus particularly on inside communication of CoC architecture. The basic idea of CoC is the creation of an architecture, which will be able to support all the requirements of a vast number of todays applications by adopting and changing its characteristics according to them. The valorization perspectives are of importance since the outcomes of this research will be applicable for embedded systems, real-time systems, communication systems, as well as for mainstream systems such as Internet-of-Things and Internet-of-Everything. As far as the inside communication of our CoC platform is concerned, we leverage on algorithms and strategies developed within the field of Software Defined Networking (SDN), which was introduced to deal with hardware redesign and ultimately provide cloud-like flexibility. At the end, we describe registration and authentication of every entity in our network.

This protocol focuses on Energy Efficiency and it is based on an existent open source protocol stack. Tania protocol framework includes a set of three protocols: The Sensors Data Transmission Protocol (Tania-SDTP), the Ad-Hoc On Demand Protocol (Tania-AHOD) and the Ad-hoc Alerts Protocol (Tania-AHA), each one servicing different user functionalities. Tania protocol is used on a specific system architecture of a crowded sensors network.
