This paper presents a framework to deal with the situation that occurs when a PU suffers harmful interference caused by the secondary use of the spectrum allocated to it. Here, the PU is assumed to be a radar system. In our proposed framework, the PU informs the database that it is suffering harmful interference. Receiving this information, the database updates the primary exclusive region (PER), where SUs are prohibited from using the licensed spectrum. The updated PER depends on the current knowledge of the SUs, which is stored in the database. We assume a circular PER centered at the primary receiver (PR) and derive its optimal radius using stochastic geometry. For each type of SU knowledge stored in the database, we evaluate the optimal PER radius for a target probability at which the PU suffers harmful interference. The results show that more detailed knowledge of the SU density and transmission powers leads to a smaller updated PER radius. Hence, a more efficient spatial reuse of the licensed spectrum is achieved.","PeriodicalId":436094,"journal":{"name":"2016 IEEE Wireless Communications and Networking Conference Workshops (WCNCW)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114541943","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}

However, the NDP initially offers no protection mechanism and is prone to address spoofing and Denial of Service (DoS). Secure Neighbor Discovery Protocol (SeNDP) is proposed to solve these NDP threats. Recently there are many solutions presented in SeNDP which relies on special IPv6 addresses named Cryptographically Generated Address (CGA). But there is little work to defend DoS attack on Duplicate Address Detection (DAD). In our paper, we focus on the problems of CGA and propose a novel time-based monitoring DoS attack. The conventional DoS defense mechanisms are realized by monitoring the packet rating and observing connection delay to analyze various DoS attack. Hence, we adopt a delay as an indication to distinct the DoS attack. We set a timer to control the address generation for monitoring abnormal attack to protect each address configuration. In addition, we adopt SHA-224 hash function instead of SHA-1 to improve the security of address generation. Considering the computation overhead, we decrease the hash matching factor from 16 bits to 8 bits. We develop our scheme using the Network Simulator (NS2) and the OpenSSL library. Finally, experiment results prove our scheme can provide more efficient IP generation. Compared with the CGA algorithm in SeNDP, our time consumption decreases to 10%. From the view of defense attack, our scheme can control DoS attack.","PeriodicalId":436094,"journal":{"name":"2016 IEEE Wireless Communications and Networking Conference Workshops (WCNCW)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122211368","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}
