Because of node mobility, the set of service components that MANET clients have at one-hop distance changes often during service provisioning. That continuous change in locally accessible services significantly increases the complexity of designing and implementing effective MANET applications. The paper claims the need of dynamic middleware supports for MANET, not only to address routing/configuration issues, but also to automate the re-qualification of service bindings at provision time. It presents COMMAND, a flexible middleware solution, based on code mobility, for transparent service rebinding in MANET. COMMAND exploits dynamically elected proxies that act as intermediaries to decouple mobile clients and needed service components. In particular, the paper focuses on how COMMAND implements a lightweight MANET-specific solution for effective code distribution to deploy the needed proxy behavior only when and where required. Finally, the paper shows the implementation of a COMMAND-based forum distributed application, together with its related performance, to point out how the proposed middleware can help service development in MANET.","PeriodicalId":122977,"journal":{"name":"1st International Symposium onWireless Communication Systems, 2004.","volume":"24 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126843950","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 conventional OFDM diversity receiver employs post-DFT combining scheme, which combines signals from a several diversity branches after DFT decomposition. However, post-DFT combining diversity requires the same number of LNAs, IF amplifiers, AD converters, and FFT processors as of diversity branches. In order to solve this problem, the authors has proposed an antenna combining diversity scheme based on electromagnetic coupled array antenna. The proposed diversity scheme requires only one set of LNA, IFA, ADC and FFT processor and gives comparable performance with the maximal ratio combining diversity in case of two-branch diversity. However, the proposed diversity has limitation in the number of diversity branches. The performance of the proposed diversity is much worse than that of the post-DFT one when the diversity branches are more than two. In order to solve this problem, joint use of antenna combining and post-DFT combining is proposed. The proposed scheme is composed of two two-branch antenna combining diversity followed by the post-DFT combining diversity OFDM receiver. The proposed diversity receiver gives the same bit error rate performance as the conventional post-DFT combining four-branch diversity scheme while it only requires two sets of OFDM receiver components.","PeriodicalId":122977,"journal":{"name":"1st International Symposium onWireless Communication Systems, 2004.","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133992123","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}
