In the internet of things (IOT), tag, reader and sensor are invisible, but they are embedded in real-world entities, which monitor and control smart devices. A key challenge of IOT is to assure high reliability software in a scalable and dynamic computing environment for data dissemination and task cooperation among sensor nodes. To effectively manage such data delivery and sensor cooperation, sensor networks may need data dissemination and cooperation protocol, such as the Sensor Data Transmission and Cooperation Service (SDTCS), which makes it easy to deal with complicated data delivery and sensor cooperation. To support higher reliability, sensor software is often required to provide updating service pack during mission execution owing to dynamic context environment. Therefore, Dynamic Software Updates (DSU) can be effectively applied for the IOT applications. This paper presents dynamic updating approach for SDTCS IOT applications. The proposed approach consists of the following:(1)one-sink-to-one-sensor;(2)one-sink-to-k-coverage-sensor;(3) multiple-sink-to-all-coverage-sensor. Performance analysis results for the suggestion protocol with different numbers of sensor nodes, different strategies are selected, which support high reliability and seamless service for SDTCS IOT applications.

A wireless sensor network (WSN) consists of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, vibration, pressure. Due to the maintenance reason, we may update the software to fix bugs. Because there are more and more sensor nodes using in the vehicle, smart environment, Software updating for wireless sensor networks has become an important issue. In previous related works, Update the node usually is required to reboot. However, reboot the nodes is costly since the previous runtime status may be lost. To recover the runtime status for routing, it will take time and bandwidth to synchronize with other nodes. We present uFlow: a programming paradigm and a prototype implementation for wireless sensor networks. uFlow allows application to update the nodes without rebooting. So we can avoid to lost precious runtime status.

This paper presents a case study of developing a distributed factory automation system model upgrade with decentralized control deployed on a network of six programmable automation controllers communicating wirelessly. The goal is to develop a distributed system which is flexible enough, and easier to reconfigure with on-the-fly online software updates in a smart factory automation environment. Our approach benefits mainly production industries which require a robust and modular software design requiring less effort for their production line. The developed solution aims at flexibility, re-configurability, ease of maintenance and reduced downtime costs.

This paper proposes a wireless embedded interface device, called a wireless software update device (WSUD), to support the task of software updates in wireless sensor network (WSN) systems and alleviate the inconvenience of updating the sensor nodes' software for users. Through the in-system trial run of its system prototype, the users could carry on the software modification and updating in order to eventually build a WSN system more suitable for the environment and the user requirements. The proposed WSUD is integrated into a sensor node for WSN software update applications. At last, transmission tests of software update files are conducted and the test results verify the functionality and feasibility of the proposed WSUD.

Future smart vehicles will employ automotive over-the-air updates to update the soft ware in the embedded electronic control units. The update process can affect the safety of the involved users, thus requires a comprehensive and elaborate security architecture ensuring the confidentiality and the integrity of the exchanged data, as well as protecting the privacy of the involved users. In this paper, we propose an automotive security architecture employing Blockchain to tackle the implicated security and privacy challenges. We describe our proof-of-concept implementation of a Blockchain-based software update system, use it to show the applicability of our architecture for automotive systems, and evaluate different aspects of our architecture.
