Advances in mobile technology have extended such collaboration scenarios including one-hop and multi-hop wireless networks. Traditional strategies to share information in wired networks are not suitable for mobile scenarios because they do not consider the disturbing networking aspects such as high disconnection rate, dynamic topology and the low bandwidth. The use of hand-held devices to share documents. This paper presents a strategy based on XML to share information in MANETs (mobile adhoc networks) using hand-held devices, considering disconnections and instability of the network bandwidth. This strategy is currently implemented in PASIR (service platform for ad hoc sharing information resources) and it can be considered by other middleware products when design the data sharing support. In addition, many group ware applications could be designed using this strategy, i.e.: distributed technical presentations, casual interactions, brainstorming, meetings for decision making and software technical reviews","PeriodicalId":247315,"journal":{"name":"2006 8th International Conference Advanced Communication Technology","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126099020","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 QOMOE detector minimizes the output variance with respect to the component equivalent to the quasi-orthogonal component to the desired user's signature waveform, then the solution is the linear minimum mean square error (LMMSE) transformation. The QOMOE receiver employs maximal-ratio combiner (QOMOE-MRC) for detecting the desired user. A comparison is made among QOMOE-MRC, matched filter (MF-MRC), decorrelator-MRC, LMMSE-MRC and blind adaptive-MRC receivers, in a Nakagami channel model. Analysis and simulation results show that the QOMOE-MRC can obtain better performance than that of LMMSE-MRC receiver","PeriodicalId":247315,"journal":{"name":"2006 8th International Conference Advanced Communication Technology","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115645748","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}

Because of this, ad hoc networks are much more vulnerable to security attacks than wired networks or infrastructure based wireless networks. Our proposed protocol incorporates an end-to-end authentication protocol that relies on a mutual trust between nodes in other clusters. The scheme strategy takes advantage of the threshold certification based end-to-end authentication protocol in large ad hoc networks. Our proposed authentication protocol uses certificates containing an asymmetric key using the threshold cryptography scheme. We present detailed security threats against multilayer cluster routing scheme. We successfully included the establishment of mutual end-to-end authentication, the prevention of node identity fabrication, and the secure distribution of provisional session keys using certification threshold key configuration by CCH (control cluster head)","PeriodicalId":247315,"journal":{"name":"2006 8th International Conference Advanced Communication Technology","volume":"509 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122758991","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}
