This paper is mainly about the design of a Wireless Energy Consumption Detector (WECD) based on the Internet of Things, combine with the IEEE802.15.4E wireless protocol. The whole system includes hardware and software parts, the choice of MCU chip, RF chip and power measurement chip for WECD, the design of each module circuit based on the chip working principle, the paper also make a key analysis of device driver module, wireless data forwarding module and wireless data showing module of indoor terminal. After a series of rigorous testing, the result indicates a high reliability and accuracy of the WECD.10aIEEE802.15.4E10aSmart home10aWireless energy consumption detector1 aFu, W.1 aShui, M.1 aChen, Y.1 aChen, L.  uhttp://www.scopus.com/inward/record.url?eid=2-s2.0-84879106063&partnerID=40&md5=32877c7463cacdf6d4cc123f5922c0a901571nas a2200205   4500008004100000245008400041210006900125260000900194300001400203490000600217520087900223653002701102653003101129653002201160653002701182100001401209700001301223700001201236856011701248       2011                        eng d00aReasoning on context satisfiability for service recommendation in mobilenetwork0 aReasoning on context satisfiability for service recommendation i  c2011  a249 - 2540 v93 aThe Ubiquitous Computing envisions a world of communicating mobile devices. As mobile devices usually have limited resources, it brings up the challenge to search and invoke services at any time and any place in an accurate, efficient and adaptive way. In this paper, we propose to filter services by matchmaking the precondition of service invocation and the context information of service consumer, in order to increase the accuracy and adaptivity of service discovery and recommendation in mobile environment. We construct context ontology to describe the environment when a service consumer submits service request first. And then, we propose to formalize the precondition of a successful service invocation based on a lightweight DL theory. Finally, reasoning on context satisfiability can be used for service recommendation. A case study shows our approach works well.10aContext Satisfiability10aPrecondition Formalization10aService Reasoning10aService Recommendation1 aKuang, L.1 aChen, L.1 aXia, Y.  uhttp://www.scopus.com/inward/record.url?eid=2-s2.0-84855397903&partnerID=40&md5=409b304a3bf247ee3b6d37e361841e41
