Future IoT systems will be deployed in open environments where the functionality of millions of IoT devices that are heterogeneous will be abstracted. In such a large scale system manual service composition is not feasible and often erroneous. A self-organizing service composition is a well known approach to deal with the problems in IoT systems. In a self-organizing service composition, the service composition is a runtime and autonomous process and human intervention is minimal. The atomic components will interact among themselves in a decentralized manner to form complex composites according to a set of self-organizing rules. The features of a self-organizing software composition are aptly suitable for the IoT domain. Smart healthcare has provided affordable healthcare for patients and enables them to self manage emergencies. This paper aims to establish the suitability of a self-organizing service composition for the smart healthcare ecosystem with special focus on real time monitoring applications.

Saving peoples live is the most important in today’s world. The best way to save lives is to have an ambulance system which is effective and can be reachable to the user/client, this paper gives the solution which focus to make the ambulance available to a nearby user/client/patient in the least possible time which will help save many lives. After extensive study and analysis new technology evolved. Navigator.geolocation method based on RestFUL Web Services is used this will help the ambulance location to be updated in the database so that it can be seen by the user who is using this application and makes it easy for him to book the ambulance. The client’s location will be pin pointed on the google map and even the ambulance which is nearby the user will be pin pointed on the map, once the patient is on board the ambulance location is taken and then the list of hospitals are pointed out on the map which helps the ambulance driver to choose the nearby hospital to take the patient on time.

awareness has become the key attribute for empowering our day-to-day systems and services to be pragmatic and distinctly powerful. Purpose-specific and generic systems, be it physical, mechanical, electrical, electronics, or computing systems are getting bestowed with enabling smartness in order to be cognitively adaptive in their actions and reactions. That is, based on the changing contexts, systems are internally as well as externally equipped to be smart in their operations, offerings and outputs. However precisely understanding the evolving contexts and feeding them into systems dynamically in time to empower them to exhibit desirable and delectable behavior are not an easy task. Thus mathematicians and computer scientists are in unison in exploring and expounding a variety of viable and venerable mechanisms and means in order to streamline and simplify the process of context-awareness. In this paper, we have zeroed down on the unique capabilities of service automata in composing atomic and discrete actions into context information on which the designated system trusts and forges ahead in accomplishing what is initially intended. We have come out with a use case in a smarter hospital environment and proved that how service automata come handy in fulfilling the intrinsic needs of context- awareness.

The medical field is continuously flooded with newer technologies and tools for automating all kinds of medical care processes. There are a variety of software solutions and platforms for enabling smart healthcare and for assisting care providers such as doctors, nurses, surgeons and specialists with all kinds of timely insights to diagnose and decide the correct course of actions. There are patient monitoring and expert systems to simplify and streamline healthcare service design, development, and delivery. However there are concerns and challenges with the multiplicity and heterogeneity of technologies and solutions. The dense heterogeneous medical devices available in the intensive therapy units pose a challenge of medical device integration. Needless to say, lot of research work has gone in devising techniques in integrating these systems for exchange of data. However mere device integration does not exploit the modern technologies until meaningful and critical information is presented to doctors and patient care personals adapting to the changes in the patient condition. The goal of this research is to apply context aware computing using service oriented architecture in acquiring, analysing and assisting doctors and nurses with necessary information for easy and critical time saving decision making. This paper presents an implementation of the identified web services which can be consumed during a treatment at the Intensive Therapy Unit (ITU).
