A simple interference analysis method was proposed through a coexistence scenario. Through calculation and simulation, a series of critical values were found. 8km and 20km of WRAN cell radius are of great significance to control the interference to DTV. If WRAN cell radius less than 8km, more than one tier of interferers are permitted. On the other hand, when WRAN cell radius exceeds 20km, the distance from DTV receiver to WRAN BS should be larger than the sum of the two radiuses (R+r).","PeriodicalId":177679,"journal":{"name":"2009 International Conference on Communication Software and Networks","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128494619","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}

Colored Petri Net (CPN) extends the traditional Petri net, it can simply the net structure, and analyze the security and correctness of complicated systems before really constructing them. We present a CPN model of role activation/ deactivation of TCAC policy, and discuss the color sets, places, arc expressions and guard functions in CPN model.

In this part, routing protocol is important to improve efficiency of Ad-hoc networks. Recently, Ad-hoc routing protocols have been studied and developed, such as DSDV, AODV, DSR, and LAR. In this paper, we propose a new routing protocol that is named by advance-LAR based on radio-range of destination node. This protocol is designed to reduce duplicate RREQ messages in the network by restrict the nodes who have a right to propagate the RREQ messages in a fixed area. In order to make sure that the RREQ message should be propagated by some nodes, there should be some nodes can get this right, so that fixed area can be changed in a special way.","PeriodicalId":177679,"journal":{"name":"2009 International Conference on Communication Software and Networks","volume":"26 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120896300","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}

Energy has become the bottle-neck problem and has constrained WSNs widely applications. Cluster mechanism has been widely pursued by the research community in order to prolong the life of WSNs. In this paper, we propose an energy-balanced mechanism based on pruning mechanism to tackle the “hot point” problem appeared in WSNs. In order to keep energy-balance, we synthetically use node’s location, residual energy and the count as cluster-head to form an evaluation function that is based on the pruning mechanism. Experimentations show that the proposed strategy can keep the energy-balance of whole cluster as well as prolong the lifetime of WSNs.","PeriodicalId":177679,"journal":{"name":"2009 International Conference on Communication Software and Networks","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126466506","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}

In modulation identification, important information may be contained in the high-order relationship among sampling points. ICA is sensitive to high-order statistic in the data and finds not-necessarily orthogonal bases, so it may better identify and reconstruct high-dimensional communication signal data than traditional time and frequency domain features. ICA algorithms are time-consuming and sometimes converge difficultly. So a modified FastICA algorithm is developed in this paper, which only need to computer Jacobian Matrix once time in one iteration and achieves the correspondent effect of FastICA. After obtaining all independent components, a genetic algorithm is introduced to select optimal independent components (ICs). The experiment results show that modified FastICA algorithm fast convergence speed and genetic algorithm optimize recognition performance. ICA based features extraction method is innovative and promising for digital modulation identification.","PeriodicalId":177679,"journal":{"name":"2009 International Conference on Communication Software and Networks","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132020661","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}
