The impact of these constraints is especially severe when traffic demands are unpredictable and characterized by random arrivals and departures. To improve the network utilization efficiency, either wavelength conversion or lightpath rerouting can be used. Since, in the foreseeable future, wavelength conversion is expected to remain an expensive technology, traffic rerouting is an attractive alternative solution to improve the network throughput conditioned by the aforementioned constraints. In this paper we propose to employ hybrid rerouting, to improve the network utilization efficiency considering a dynamic traffic model. Hybrid lightpath rerouting combines passive rerouting and active rerouting. Our proposed algorithm, namely, Sequential Routing with Hybrid Lightpath Rerouting algorithm (SeqRwHLR) establishes the traffic demands sequentially, that is demand by demand at arrival dates. When an incoming traffic demand cannot be set up in the absence of path-free wavelengths between its source and destination nodes, the SeqRwHLR algorithm performs passive rerouting procedure aiming hopefully at freeing a path-free wavelength to service the new traffic demand. Furthermore, our proposed algorithm dynamically reroutes some already established lightpaths from longer paths to vacant shorter ones so as to reduce the network resources consumption. This should hopefully lead to a better performances. The performances of the proposed algorithm are demonstrated to be promising through simulation results.","PeriodicalId":270622,"journal":{"name":"2014 Global Summit on Computer & Information Technology (GSCIT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122609619","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}

Resource limitations have to be taken into account when designing a WSN infrastructure. Authentication in WSNs is critical, as they are often deployed unattended in hostile environments and must transmit information over unsecured mediums. However, the cost of performing cryptographic operations is an extremely limiting factor because sensor devices and related equipment are constrained by storage and computational ability. Hash functions are the most widespread among all Authentication primitives, and are currently used in multiple cryptographic schemes and in security protocols. This paper presents a new Secure Hash Algorithm called (2AMD-160) which uses a famous structure of hash algorithm given by the MIT Laboratory for Computer Science and RSA Data Security, Inc. To demonstrate the effectiveness of 2AMD-160 in terms of security and execution time, we compare our approach with two methods namely, MD5 and SHA1 hash function algorithms. Simulation results demonstrate that the execution time and the security achieved by the proposed method are more effective than the MD5 and SHA1.","PeriodicalId":270622,"journal":{"name":"2014 Global Summit on Computer & Information Technology (GSCIT)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129834274","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}
