Abstract
Pervasive service composition is useful in many scenarios, for instance, in urban planning or controlled harvest. Currently, there is no standard to develop solutions using pervasive service composition. However, big companies propose their frameworks to develop complex services, but their frameworks are appropriate in specific applications, such as home automation and agriculture. On the other hand, there are different very well-grounded academic proposals for pervasive service composition. However, these do not solve the problems of traditional approaches that are appropriate to specific areas of application, and adaptation is needed to deal with the dynamism of the environment. This article presents a cognitive approach for pervasive service composition where InfoCom devices and the implementation of cognitive functions interact to create pervasive composite services. Our central hypothesis is that cognitive theory can help solve actual problems requiring pervasive service composition, as it addresses the above-mentioned problems. To test our approach, in this article we present a case of urban insecurity. Specifically, in different countries, street robbery using firearms is one of the problems with a high impact because of its frequency. This article proposes to compose a pervasive service for deterring criminals from committing their crimes. The results obtained by simulating our proposal in our case study are promising. However, more research needs to be achieved before applying the proposed approach to actual problems. The research needed ought to address various problems, some of which are discussed in this article.
Highlights
Cities are becoming more complex environments to live in; for instance, we need to localize specific places, prevent some incidents, among many others
This proposal for pervasive service composition, or PSC, is motivated mainly by two facts: the evident increase of technology in our daily lives, and the lack of an appropriate way to compose pervasive services dealing with problems that involve the dynamism of the environment
Everywhere we look we see the use of cameras, speakers, drones in the streets, factories and controlled harvest environments, not to mention the use of more and more powerful technology on people through wearables such as mobile phones, glucometers and many other types of sensors
Summary
Cities are becoming more complex environments to live in; for instance, we need to localize specific places, prevent some incidents, among many others. The technologies present in this kind of environment, including the ones humans wear, may help overcome some of our human problems. In order to use these technologies to help humans in dynamic environments, two problems must be solved. The first one is the autonomous pervasive service composition required by humans to deal with complex problems that a single service cannot solve. The second is how to deal with the volatility of available services in the environment. How to ensure that the service is useful by the time it is created, and during the time it is required. We deal only with the first problem. The objective of this article is to present a new way to create pervasive composite systems. The inspiration for our proposal is the way the human mind composes solutions using its cognitive functions
