Composable context aware services [guest editorial]
Raj Yavatkar;Andrew Campbell;Lakshman Krishnamurthy;Tarek Abdelzaher
Publication Year: 2008,Page(s):4 - 5
The seven articles in this special issue focus on composable context aware services. The articles roughly fall into four areas: a survey of ambient networks, extensions to network protocols to facilitate service discovery and composition, networking middleware and software frameworks for integration of context awareness in service composition, and an example of creating an ecosystem to build conte...Show More
Composable context aware services [guest editorial]

Year: 2008 | Volume: 22 | Issue: 4
Ambient networks, a product of a European union sixth framework project, is a novel networking paradigm for beyond 3G. It aims at the ubiquitous provisioning of existing and new services over any access technology and any type of network. Network composition is a core feature of ambient networks. It enables on-demand and transparent cooperation between heterogeneous networks, with little or no pre...Show More
Enabling rapid wireless system composition through layer-2 discovery
Shivani Sud;Roy Want;Trevor Pering;Barbara Rosario;Kent Lyons
Publication Year: 2008,Page(s):14 - 20
Although small mobile computers have processors whose capabilities are increasing, often they still are resource constrained in terms of performing many common computing tasks. Composition is a technique that overcomes this limitation by wirelessly connecting several nearby devices together to share their resources to create a logical platform that is better suited to a given task. However, curren...Show More

On composability of localization protocols for wireless sensor networks
Publication Year: 2008,Page(s):21 - 25
Cited by: Papers (11)
Realistic, complex outdoor environments pose significant challenges for node localization in wireless sensor networks. In spite of the fact that many elegant and clever solutions have been proposed, no robust localization system has emerged. This status quo is because existing solutions work well for single sets of assumptions that, however, do not always hold in complex environments. In this arti...Show More

Context-aware wireless sensor networks for assisted living and residential monitoring
Anthony D. Wood;John A. Stankovic;Gilles Virone;Leo Selavo;Zhimin He;Qiuhua Cao;Thao Doan;Yafeng Wu;Lei Fang;Radu Stoleru
Publication Year: 2008,Page(s):26 - 33
Improving the quality of healthcare and the prospects of "aging in place" using wireless sensor technology requires solving difficult problems in scale, energy management, data access, security, and privacy. We present AlarmNet, a novel system for assisted living and residential monitoring that uses a two-way flow of data and analysis between the front- and back-ends to enable context-aware protoc...Show More
HiCon: a hierarchical context monitoring and composition framework for next-generation context-aware services
Kyungmin Cho;Inseok Hwang;Seungwoo Kang;Byoungjip Kim;Jinwon Lee;Sangjeong Lee;Souneil Park;Junehwa Song;Yunseok Rhee
Publication Year: 2008,Page(s):34 - 42
This article presents a hierarchical context monitoring and composition framework that effectively supports next-generation context-aware services. The upcoming ubiquitous space will be covered with innumerable sensors and tiny devices, which ceaselessly pump out a huge volume of data. This data gives us an opportunity for numerous proactive and intelligent services. The services require extensive...Show More
Composing semantic services in open sensor-rich environments
Publication Year: 2008,Page(s):44 - 49
Cited by: Papers (11)
Networked sensing promises to drastically change the way people interact with their environments by providing rich contextual information in real time. Major challenges remain on how concurrent users program and control such environments at the application level. This paper summarizes our research efforts in automatically composing semantics services to fulfill declarative user queries in resource...Show More

One of the most compelling social questions, which until now was left unanswered by current technology, is "Who's that?" This question is usually asked about a new unfamiliar person in a social setting who piques your curiosity. This article presents WhozThat, a system that ties together online social networks with mobile smart- phones to answer this common and essential social question. WhozThat ...Show More
