In this paper, we propose a deflection-compensated BvN (D-BvN) switch to enhance the performance. The D-BvN switch provides capacity guarantee for each virtual circuit (VC) by the BvN decomposition of average input traffic matrix, while copes with traffic burst by deflection. In particular, deflection scheme fully utilizes the spare capacity of starving VCs to deflect overflow traffic to other VCs and provide bandwidth for deflection traffic to re-access its desired VC. Analytical and simulation results show that it can achieve close to 100% throughput of offered load and the packet out-of-sequence probability is also negligible.","PeriodicalId":210863,"journal":{"name":"Wireless and Optical Communications Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114351018","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 this approach, the polarization characteristics of transmitting and receiving antennas are controlled by a varying regularity rather than remaining fixed, which is equivalent to scramble the polarization characteristics of antennas. If the eavesdropper doesn't know the varying regularity, it will never recover the original transmitting signals correctly, which guarantees the security of the proposed approach. The simulated results demonstrate that the proposed approach indeed can provide high secrecy capacity and low BER for the legitimate receiver, and it can still achieve positive secrecy capacity even though the legitimate receiver's channel is worse than the eavesdropper's.","PeriodicalId":210863,"journal":{"name":"Wireless and Optical Communications Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117223505","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}
