Framework para Gestão de Dispositivos Móveis: módulo inventário

Dissertação de Mestrado em Engenharia InformáticaO número e diversidade de dispositivos móveis utilizados em contexto pessoal e contexto empresarial é um fenómeno em franco crescimento. Este fenómeno conhecido como Bring Your Own Device (BYOD) é um dos desafios que as empresas têm de enfrentar. Se por um lado o BYOD promove a satisfação pessoal e a produtividade, por outro, a gestão de dispositivos móveis e a segurança dos dados tornam-se mais complexas. Existem várias soluções no mercado, apontadas como partes vitais da infraestrutura empresarial, no processo de gestão de dispositivos móveis (Mobile Device Management – MDM). Uma vez que tendem a agregar inúmeras funcionalidades, são conhecidos alguns problemas associados a estas soluções, como por exemplo a invasão da privacidade nos dispositivos pessoais e a possibilidade de disrupção com outras soluções em uso nas empresas, para além de outros. Para evitar esta situação propomos a criação de uma framework modular para a gestão de dispositivos móveis, com uma abordagem focada na segurança dos dados organizacionais e na separação do contexto user vs enterprise. A framework será baseada em Web Services, e o objetivo é o de permitir que uma empresa adote ou integre apenas os serviços necessários, reduzindo o número de aplicações em uso e o custo de propriedade. O primeiro módulo a implementar é o de inventariação de dispositivos móveis.The number of personal mobile devices used inside company’s network continues to grow. This phenomenon known as Bring Your Own Device (BYOD) is one of the challenges the companies have to face sooner or later. In one hand, BYOD improve staff satisfaction and productivity, in the other, the mobile devices management and data security get more complex. There are several solutions in the market pointed as vital part of enterprises infrastructure for mobile devices management (MDM), however, some issues arise with these solutions. Privacy invasion in personal devices, and disruption with legacy systems due to several functionalities aggregation is some of them. To avoid this problem, we propose a modular framework for mobile devices management, with an approach focused in organizations data security and users versus enterprises context separation. This will be a Web Service based framework, and the goal is to allow that companies can use or adopt only the necessary services, cutting unnecessary applications and reducing costs of ownership. The first module to develop is an inventory system for mobile devices

A lightweight data interchange format for Internet of Things in the PalCom middleware framework.

We present the PalCom Object Notation, a textual data representation format for communication between internet of things which support binary and textual data. The format does not require parsing of user data (or the “payload”) and is thus efficient to use also for large binary values such as digital images, audio and video as well as for short textual values. These can be mixed in the same messages and thus transported over the same communication link. Its structure is influenced by JSON, making it easy to translate between the two formats. The evaluation show that its size and processing efficiency is comparable to that of JSON for small data, but becomes both smaller and more efficient as data grows, and can yield a tenfold performance increase for binary payloads

A lightweight data interchange format for internet of things with applications in the PalCom middleware framework

We present the PalCom Object Notation, a textual data representation format for communication between internet of things which support binary and textual data. The format does not require parsing of user data (or the “payload”) and is thus efficient to use also for large binary values such as digital images, audio and video as well as for short textual values. These can be mixed in the same messages and thus transported over the same communication link. Its structure is influenced by JSON, making it easy to translate between the two formats. We show how it fits seamlessly into the common situation with JavaScript on a client side and Java on a server side, combined by a HTTP-server. The performance evaluation shows that the size of the representation and the time needed to generate and parse it is comparable to that of JSON for small data sizes, but becomes both smaller than JSON and faster to process as data sizes grows, and can yield a tenfold performance increase for binary payloads
