JXTA-SOAP: Implementing Service-Oriented Ubiquitous Computing Platforms for Ambient Assisted Living

Abstract. The challenging context of Ambient Assisted Living (AAL) demands for a service-oriented technological shift in the field of ubiqui-tous computing. Recently, novel paradigms have been proposed, most of them envisioning arbitrary pairs of peer application entities communi-cating and providing services directly with each other and to users. In order to enforce these paradigms even to systems which include devices with limited processing and storage resources, lightweight middleware components are required. JXTA-SOAP, a portable software component supporting peer-to-peer sharing of Web Services, is a suitable solution. We illustrate its features and a possible deployment to enable AAL ser-vices. Key words: ubiquitous computing, ambient assisted living, services, peer-to-peer
