The serverkernel operating system

ABSTRACTWith the idea of exploiting all the computational resources that an IoT environment with multiple interconnected devices offers, serverkernel is presented as a new operating system architecture that blends ideas from distributed operating systems, Unikernel, and LWK. These concepts are mixed with a server in which a user can remotely offload computations and get the result. This single space-address operating system (OS) can be interpreted as a bare-metal OS in which only drivers for CPU, network, and accelerators are required in order to provide service. To demonstrate the advantages of serverkernel, jonOS, an open-source C implementation of this architecture for Raspberry Pi, is provided. Compared with commercial architectures used in IoT devices, serverkernel achieves an improvement ratio of 1.5 in CPU time, 2.5 in real-time, and around 9 times better in network speed.
