In the future, we will see many ad hoc network applications, which are very important for realizing ubiquitous environments. The topology of ad hoc networks may change. For this reason, the routing protocols play an important role for construction of ad hoc networks. In this paper, we propose a new zone based routing protocol, which reduces the number of control packets. In the conventional routing protocols, the control packets are transmitted periodically. However, in the proposed protocol, the control packets are only transmitted when nodes are moving. The performance evaluation via simulations shows that the proposed protocol has a good performance and power consumption characteristics than conventional protocols.","PeriodicalId":196401,"journal":{"name":"2010 International Conference on Broadband, Wireless Computing, Communication and Applications","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128993840","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}

Most of previously proposed digital rights management mechanisms focus on the protection mechanisms for digital contents and pay less attention to the discussion on business models and users’ convenience. It will decrease effective distribution for digital contents and the intentions of users’ usage. With the super distribution model, we first propose a digital rights management system that increases distribution channels to increase the efficiency of distribution for digital contents. Then, we implement the proposed digital rights management system by using the API Hook with Microsoft Foundation Classes (MFC) as a wrapper. The implemented digital rights management system can achieve content protection without sacrificing user’s convenience. In addition, the proposed digital rights management system satisfies the following requirements: description, identification, transaction, protection, monitoring, tracing, super distribution, transparency, and portability.","PeriodicalId":196401,"journal":{"name":"2010 International Conference on Broadband, Wireless Computing, Communication and Applications","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115952681","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}

Second we investigate the effect of clutter due to back scattering from the random rough surface on the radar cross section (RCS) of the target. Finally we show some numerical examples for back scattering from a target above a Gaussian type of random rough surface with arbitrary height deviation and correlation length. It is demonstrated that the clutter is predominant in the back scattering and it is mainly caused by the diffraction related to reflection from the random rough surface.","PeriodicalId":196401,"journal":{"name":"2010 International Conference on Broadband, Wireless Computing, Communication and Applications","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128244432","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}

Numerical examples are carried out for the well-known three diffraction problems, and it is shown that both the accurate and approximate solutions are in good agreement.

By efficiently combining redundancy with extra defense mechanisms, we attempt to ensure the continuity of a network service, and enhance its survivability against malicious attackers that utilize accumulated experience. We construct an attack/defense scenario, in which an attacker and a defender compete against each other, and formulate it as a two-phase nonlinear integer programming problem. We adopt a Lagrange an Relaxation-based solution approach to resolve the above problem, and further prove the efficacy of our approach by computer experiments. The result shows LR-Based attack algorithm is better than other strategies we compared. Further, no matter what kind of attack/defense cost function is adopted, the LR-Based allocation algorithm can always provide a much better defense capability than others.","PeriodicalId":196401,"journal":{"name":"2010 International Conference on Broadband, Wireless Computing, Communication and Applications","volume":"356 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132883561","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}
