We derive the multilinear-based approaches which utilize no knowledge for direction of arrival (DOA) or polarization information. The quadrilinear-based approach has better bit-error-rate (BER) performance than the trilinear-based one. The newly designed blind quadrilinear receiver indicates quite close performance to nonblind MMSE method, supports small number of snapshots, and also exhibits blind robust characteristics.

In cluster construction stage, according to the various sensor node types in CADC algorithm, the same types of nodes is divided into the same cluster and different types of nodes can not be divided into the same cluster. In the cluster heads selection scheme, nodes with the most residual energy will be elected cluster heads first. Cluster heads with the same type further integrat into the secondary cluster. Because this algorithm makes the data aggregation to be the most optimal and reduces the transmission distance of cluster heads, it can prolong the lifetime of the whole networks.","PeriodicalId":280001,"journal":{"name":"2009 International Conference on Wireless Networks and Information Systems","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117048063","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}

The scientists have already conducted the extensive research. In order to perfect the protocol, an improved protocol LAODV is proposed in this paper, which has two improvements. One improvement is that LAODV involves a delayed algorithm based on node state. It adopts a novel delayed broadcast scheme which combines the shortest route selection criterion with the node states including power and traffic load to select the intermediate nodes during the route discovery phase; The other is that a backup reverse path between the intermediate nodes and the source request nodes is established, when the route breaks down, it makes sure that the intermediate node can still work smoothly. By analysing the simulation results of LAODV, the performance is demonstrated.","PeriodicalId":280001,"journal":{"name":"2009 International Conference on Wireless Networks and Information Systems","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116066632","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}

Medical is no exception to this phenomenon, whereas individuals are trying to save lives instead of making profit in hospital. Researcher in information systems domain agreed that use of wireless portable system in hospital could improve quality of care, cost reduction, error reductions, and better information quality. Awareness and use of information communication technologies (ICT) are on the rise in China and uptake of the wireless system in hospital is relatively slow. This paper present the initial finding of the data collected from traditional Chinese medical professionals regarding their opinions and views about the use of wireless portable system in hospital. Total of 100 surveys were distributed and 86 useable surveys were returned, data was analyzed through SPSS software. Factor analysis through SPSS analysis clearly shows that Chinese hospital professionals are concerned about the usefulness and outcome offered by the system itself.","PeriodicalId":280001,"journal":{"name":"2009 International Conference on Wireless Networks and Information Systems","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120943372","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}
