Since, it improves energy efficiency, lifetime, robustness, precision and so on. The final goal of WSN is Smart Dust. So, WSN devices can't use expensive crystals. Although diversity algorithms were proposed for Time Synchronization, most of the algorithm have disadvantage when they get out from their assumptions. Especially, Byzantine Failure and malicious node occurred in local environment, make a bad effect on time synchronization. Therefore, we need to consider time synchronization in global aspect to avoid environment problems. This paper proposes the supplement algorithm for time synchronization in global aspect, and evaluates the algorithms with NS2. This performance is better by 10 percents than existing algorithm.","PeriodicalId":222874,"journal":{"name":"2009 International Conference on Cyber-Enabled Distributed Computing and Knowledge Discovery","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116715478","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 paper, a digital watermarking algorithm is proposed based on integer wavelet transform to protect digital images and estimate its integrity and authenticity. Using matrix norm quantization, watermarks are embedded into low-frequency, medium-frequency and high-frequency detail sub-bands of images' integer wavelet domain. Based on this, we develop a blind-testing watermarking algorithm. Experimental results show that the developed algorithm achieves robustness and sensitivity. It can also exactly locate the distorted area.

The problem is to assign channels to links in the network with the original topology preservation, and aim at minimizing the overall network interference which is proved to be NP-hard. We have first illustrated that the conversion from the channel assignment problem to the Max k-cut or Min k-partition problem cannot correctly evaluate the network interference because of the broadcasting characteristic of the wireless communication in wireless networks. In this paper we have developed a centralized heuristic algorithm for the channel assignment due to the NP-hardness of the problem. Extensive simulation results have demonstrated that our algorithm has good performance in both dense and sparse networks compared with related works. The theoretic and experiment results have shown that the proposed algorithms serve as a practical solution to the channel assignment problem in the multi-channel multi-radio wireless mesh networks.","PeriodicalId":222874,"journal":{"name":"2009 International Conference on Cyber-Enabled Distributed Computing and Knowledge Discovery","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115441788","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}

Assuming that the channel band is divided into multiple subchannels, symbols are transmitted on two frequency hopped subchannels simultaneously. To keep the total transmission power constant, the signal power in each of the two subchannels is reduced to half of what would be in single channel transmission. At the receiver selection diversity is collected by decoding the subchannel with a large gain. Furthermore, channel diversity can be obtained by combining complex-field coding (CFC) with the dual carrier selection design. We show that the effect of our design is similar to that of orthogonal frequency division multiplexing (OFDM), but ours achieves higher data transmission rate and collects selection diversity at the expense of increased implementation complexity. Numerical simulations are provided to validate the theoretical analysis.","PeriodicalId":222874,"journal":{"name":"2009 International Conference on Cyber-Enabled Distributed Computing and Knowledge Discovery","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125561812","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 methods assume an ideal link layer model when increasing the lifetime of wireless sensor networks and energy saving techniques using geographic routing remains largely unexplored. Based on a realistic link layer model, we propose a novel geographic routing algorithm to prolong the lifetime of wireless sensor networks. In our method, a packet is forwarded to the optimal neighbor by evaluating of each neighbor's characteristic based on four important factors: PRR (Packet Reception Rate), forwarding history, progress and remaining energy. Simulation and comparison results show that our algorithm can greatly increase the lifetime of wireless sensor networks.","PeriodicalId":222874,"journal":{"name":"2009 International Conference on Cyber-Enabled Distributed Computing and Knowledge Discovery","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132733799","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}
