A new optimal receding horizon filter is composed largely of two sets of equations. The sets of Lyapunov equations and the celebrated Kalman equations fully describe the proposed filter.

In this paper, we proposed a collaborative approach (CS-SCTP) for secure SCTP communication in a wireless environment. CS-SCTP employs two mechanisms, partial authentication and two- level key encryption, to preserve the performance advantages in Collaborative SCTP (C-SCTP) and the security enhancement in Secure SCTP (S-SCTP). In the simulations, the performance results show that CS-SCTP outperforms S-SCTP and is comparable to C-SCTP.","PeriodicalId":384583,"journal":{"name":"TENCON 2007 - 2007 IEEE Region 10 Conference","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125524834","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}

This paper presents a fast direction detection algorithm to effectively reduce the number of the possible candidate modes for H.264 intra prediction. The proposed fast algorithm is based on the direction detection of the edge inside the block. Instead of full intra mode search, the proposed method only searches 4 modes for 4times4 luminance blocks, and 2 modes for 16times16 luminance and 8times8 chrominance blocks. Experimental results reveal that the proposed algorithm significantly reduces the encoding time over 60% in average with slight loss in bit-rate and PSNR.","PeriodicalId":384583,"journal":{"name":"TENCON 2007 - 2007 IEEE Region 10 Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129411475","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 technique used in compressing text allows searching phrase in the compressed form without decompressing the compressed file.

There are many fundamental problems that sensor networks research will have to address in order to ensure a reasonable degree of cost and system quality. Cluster formation and cluster head selection are important problems in sensor network applications and can drastically affect the network's communication energy dissipation. However, selecting of the cluster head is not easy in different environments which may have different characteristics. In this paper, in order to deal with this problem we propose a power reduction algorithm for sensor networks based on fuzzy logic. We evaluate the proposed method by simulations and show that proposed system makes a good selection of the cluster head.","PeriodicalId":384583,"journal":{"name":"TENCON 2007 - 2007 IEEE Region 10 Conference","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128276409","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}
