A Self-managed Marketplace for Sharing IoT Sensors

Internet of Things (IoT) applications can significantly reduce the cost and timeframe of providing their benefits by taking advantage of the billions of existing IoT sensors and other IoT devices that have been deployed by others in IoT. This paper proposes a self-managed Sensor Sharing Marketplace (SenShaMart) that allows IoT applications to discover, integrate, and pay for the use of sensors that are managed by different parties. In addition to being a self-managed IoT marketplace, SenShaMart is fully autonomic and cannot be controlled by any specific party. IoT applications and IoT sensor providers interact via SenShaMart provided services for semantic description of IoT sensors and their data, semantic query processing, automatic integration of sensors and their data, and IoT sensor payment transactions that control the access to the flow of sensor data according to the sensor payment terms. Self-management and full autonomy are achieved via a specialized SenShaMart blockchain that keeps and manages all data needed by the SenShaMart services that encapsulate it. The paper presents the SenShaMart architecture and service organization, its specialized blockchain, as well as its current performance characteristics and future research.
