“…After the body of the function is processed, we inject a line of code that instantiates the appropriate Scope object at the beginning of the function being instrumented (lines [17][18]. Finally, since the function being instrumented is itself an object belonging to the parent scope, we create a line of code that will add the function to its parent scope (line 19 Instrumenting a VARDECL node is more straightforward (lines [21][22][23][24].

ThingsMigrate: Platform‐independent migration of stateful JavaScript Internet of Things applications

The Internet of Things (IoT) has gained wide popularity both in academic and industrial contexts. Unlike traditional embedded devices with specialized firmwares, modern IoT devices accommodate general‐purpose operating systems, allowing developers to run more sophisticated applications written in high‐level languages like JavaScript. Because IoT devices are subject to resource constraints like available battery power, we need to dynamically migrate a running process between different devices to prevent losing state. However, it is challenging to apply migration techniques using memory snapshots across the heterogeneous pool of IoT devices. We present ThingsMigrate, a middleware providing platform‐independent migration of JavaScript processes across IoT devices. Prior to execution, ThingsMigrate instruments the source code of a given program to expose its internal state. During run‐time, the transformed program produces on demand a JSON snapshot of its current state, from which new code is generated to resume execution. Thus, ThingsMigrate enables process migration entirely in the application space without any modifications to the underlying virtual machine (VM), providing VM‐independence. We present three versions of ThingsMigrate, each building on the previous to optimize for run‐time latency and memory consumption. We report on the experience of building each successive version and discuss the insights gained and the learning outcomes. We evaluated ThingsMigrate against standard benchmarks, over two IoT platforms and a cloud‐like environment. We show that it can migrate even highly CPU‐intensive applications, with average run‐time latency overhead of 33% and memory overhead of 78%. ThingsMigrate supports multiple subsequent migrations without introducing additional overhead over each subsequent migration.

“…We can expect that new technologies such as blockchain will reduce this problem, introducing data interoperability, and security [4] and by the adoption of international standards for EHRD (Reference Model, ISO/DIS 13606-2, OpenEHR) [5][6][7][8]. However, we are just in the time when leveraging the power of health data to improve clinical or administrative decisions still requires an important effort to ensure the requested data quality.…”

Data Integrity and Quality

Data collection in health programs databases is prone to errors that might hinder its use to identify risk indicators and to support optimal decision making in health services. This is the case, in colo-rectal cancer (CRC) screening programs, when trying to optimize the cut-off point to select the patients who will undergo a colonoscopy, especially when having insufficient offer of colonoscopies or temporary excessive demand. It is necessary therefore to establish “good practice” guidelines for data collection, management and analysis. With the aim of improving the redesign of a regional CRC screening program platform, we performed an exhaustive analysis of the data collected, proposing a set of recommendations for its correct maintenance. We also carried out the curation of the available data in order to finally have a clean source of information that would allow proper future analyses. We present here the result of such study, showing the importance of the design of the database and of the user interface to avoid redundancies keeping consistency and checking known correlations, with the final aim of providing quality data that permit to take correct decisions.

Sharing a file that contains multimedia data among the different peers of wireless Internet of Things (IoT) networks has several challenges. One of the main challenges is their centralized system, which leads to high‐security risk and low user reachability. One solution could be to simply change the system to a decentralized network by using the blockchain network to store these files. However, it may solve the low user reachability and security problem at the cost of low latency, longer response time, scalability and privacy issues. Therefore, this article uses the advanced blockchain scheme and distributes InterPlanetary File System. We also presented the system framework and its working. Finally, we do the security analysis of our proposed system and found that it has strong potential to solve most of the security challenges that traditional system faces. Moreover, our proposed approach can be applied to any file‐changing wireless IoT network that needs to exchange multimedia data such as healthcare data, IoT data in wearable devices, traffic data in smart cities, etc.
