However, conventional centralized and broadcasting based network association mechanisms may consume large energy, and distributed network association mechanisms may suffer from addressing failure when applied to large scale WSNs. In this paper, we consider distributed network association with scalability for the construction of a large scale WSN. The proposed mechanism constructs a large scale addressing tree before network initialization. Based on the addressing tree, it allows each router to have its own addressing space which will be used for unique addressing of its child nodes. Then, a novel parent/child selection algorithm can assign routers to be located throughout the whole deployment area. Thus, nodes can join the network in the presence of sufficient neighbor routers and receive a unique address in a distributed manner. Finally, the performance of the proposed scheme is evaluated by computer simulation, showing remarkable performance improvement over conventional schemes when applied to a large scale WSN.","PeriodicalId":321031,"journal":{"name":"IEEE/ACM International Conference on Green Computing and Communications","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125668800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While most of the existing efforts on Web of Things are focused on device mash up and data collection, in this paper a semantic web of things framework is proposed to leverage Semantic Web as the unified mechanism for monitoring, tasking, presentation, information flow and collaboration. Firstly, the requirements of human centric web of things application are described. Then the active linked data with data, task, context, computational organization, knowledge, presentation and interaction models is defined by extending the conventional linked data. Based on the active linked data models, we propose a semantic Web of Things framework, which leverages multiagent technologies to facilitate human-to-human and human-to-machine collaborations. Finally, a sample case on care coordination and ubiquitous health service roaming is given. This paper demonstrates how these technologies and architectures significantly enhance the capability of Web of Things for human centric applications.","PeriodicalId":321031,"journal":{"name":"IEEE/ACM International Conference on Green Computing and Communications","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134397878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To realize IoT service, access points are needed for heterogeneous terminals, sensors, actuators, laptop and mobile terminal. Wireless Mesh Network (WMN) could be a good solution. WMN consists of mesh points (MPs) that serve as a relay for other MPs for extension of network coverage. Reliable service coverage is given for network users who suffer from lack of wired infrastructure. WMN has self-recovery scheme, so it gives reliability and cost-effective. Most researches about WMN consider MPs without mobility. However, mobile MPs could give flexibility to IoT network. In this paper, MPs have mobility for flexible IoT services. It is considered that terminals which have same characteristics form a cluster and mobile MP gives access to those terminals. However, mobility of MPs degrade performance of network, packet success ratio, delay and jitter. Especially, frequent link breakages and extended hidden nodes problem occur. In this paper, Group mobility based clustering and multi-channel MAC schemes are used to overcome results of mobility. Moreover, cluster-based multi-channel framework is suggested for reliable wireless communication for IoT services.","PeriodicalId":321031,"journal":{"name":"IEEE/ACM International Conference on Green Computing and Communications","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128371079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, energy limitations on mobile platforms will reduce the performance and sustainability. Code offloading mechanisms partition application codes and offload partial workloads to remote servers for energy savings. However, code offloading effect tends to be challenged by network transmissions as desired responsiveness maybe violated. Thus, the decisions on partitioning granularity become pivotal. In this paper, we propose a two-phase partitioning mechanism called MACO which maintains both the application responsiveness and a manageable granularity. We find that transmitting UI information is inefficient in network communication. So application codes are automatically divided into computational and UI-related segments firstly, where the latter ones are preferred to run locally. Secondly, the programmer can fine tune the intermediate partitioning result with a visual tool. We implemented MACO in web browsing applications written in HTML5/JavaScript codes. Evaluations on both real-world and simulated workloads show it reduces the response time (and corresponding energy) by up to 91% while the granularity is easy to manage.","PeriodicalId":321031,"journal":{"name":"IEEE/ACM International Conference on Green Computing and Communications","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125003043","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
