For a long time, researchers have made great efforts to efficiently utilize the limited energy storage of sensors. Recently, it was shown that external energy resources can be harvested by the sensors in order to increase their lifetime. This paper elaborates on the role of recharging in energy efficiency for wireless sensor networks. Particularly, several energy efficiency scenarios with recharging are discussed. The new facets brought by recharging are highlighted. A representative example is provided to show the advantage of recharging in sensor networks. This paper is dedicated to serve as a tutorial which calls for more attention to the exciting research topic-recharging for wireless sensor networks.","PeriodicalId":448094,"journal":{"name":"2010 International Conference on Wireless Communications & Signal Processing (WCSP)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134067127","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}

The secondary user is able to simultaneously observe more than one channel. We consider a sequential decision setup. After taking each sample, the secondary user should decide either to stop or continue scanning. If the secondary user decides to stop scanning, it then needs to make decisions on the busy/idle status of each channel. If the secondary user decides to continue scanning, it then needs to select a subset of the channels to sense. Two scenarios are investigated. In the first scenario, there is a strict delay constraint on the scanning process. That is, the spectrum scanning needs to be completed within a certain period of time. In the second scenario, there is no strict delay constraint. That is, the spectrum scanning continues until the completion of the detection process. In both scenarios, optimal algorithms for multichannel scanning with multiple simultaneous observations are developed to minimize a cost function that strikes a balance between detection error probabilities and detection delay. Low-complexity approximation schemes are also developed to reduce the complexity of the optimal schemes. Simulation examples are provided to illustrate the effectiveness of the proposed algorithms.","PeriodicalId":448094,"journal":{"name":"2010 International Conference on Wireless Communications & Signal Processing (WCSP)","volume":"190 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124285544","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}

Almost every upper layer application such as routing or self-organizing relies on neighbourhood tables. Imprecise tables may lead to failures that may be costly in terms of resources which are very limited in such networks. Neighbourhood tables are achieved thanks to the Hello protocol. Several studies propose smart schemes to dynamically adapt the frequency of Hello messages but none of them investigates the way the refreshment period of entries in table should be adapted. In this paper, we introduce the Neighbourhood Lifetime Algorithm (NLA), the very first algorithm that adapts dynamically the refreshment period of entries in neighbourhood tables, based on the speed of node and the frequency of the Hello message. Our simulation results show and demonstrate the efficiency of NLA and its high performance to keep neighbourhood tables consistent.","PeriodicalId":448094,"journal":{"name":"2010 International Conference on Wireless Communications & Signal Processing (WCSP)","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125586765","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}

The registration parameters are translation and rotation. This method assumes images like charged materials that attract each other. In this case, one of the images moves in the same direction as the applied force while the other one is still. The movement of the image continues until the resultant force becomes zero. This approach estimates the registration parameters simultaneously and leading to a better optimized set of registration parameters. The registration error for this method is 1 to 3 pixels. In this paper we aim to develop this method for the applications which need sub-pixel accuracy. First, by applying the Canny edge detector on the input images, the edge information is also used for the registration process to increase the robustness of this method in the presence of noise. After that, sub-pixel accuracy is provided for this method by using interpolation techniques.","PeriodicalId":448094,"journal":{"name":"2010 International Conference on Wireless Communications & Signal Processing (WCSP)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134411476","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}

We propose a cooperative approach to make each CR-Tx know the interference level at the PU-Rx when there is no central control node in the network and no assistant sensors are deployed to do the interference measuring jobs. The power control problem is proved to be a convex problem. Since the powers of CR-Tx nodes are coupled in constraints, we apply the Lagrange relaxation of the coupling constraints method and construct the subgradient iterative algorithm to solve the dual problem in a distributed way. To reduce the payload of the message exchange at each iterative process, an improved algorithm is proposed that could be implemented through Lagrange dual decomposition. Numerical results show that the two algorithms can converge very fast. When the delay constraints of CR users are not very small, it is better to apply the improved algorithm which has a good performance but with a much lower complexity.","PeriodicalId":448094,"journal":{"name":"2010 International Conference on Wireless Communications & Signal Processing (WCSP)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116300914","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}
