Energy efficient is one of the most important issues to be considered when WSN is deployed. Within a sensor node, dynamic power management (DPM) is an effective method to extend the lifetime of WSN. In this paper, we firstly introduce the character of the redundant nodes in WSN, and discuss a novel method to decide which nodes are the redundant nodes based on the same event that nodes sensed. Then, in order to effectively shut down the components of each node based on the observed event statistics, we propose a new sleeping policy integrating with dynamic voltage scheduling (DVS) technique and modify the sleep threshold for each state. Simulation results show that the energy consumption is significantly reduced by using the proposals above.","PeriodicalId":348778,"journal":{"name":"2010 2nd IEEE InternationalConference on Network Infrastructure and Digital Content","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130591801","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}

But the scarcity of spectrum resource below 1GHz is one of the most serious problems in the deployment of LTE TDD. Digital Dividend spectrum, which is free up for the conversion from analog TV to digital TV, is the ideal frequency band to deploy LTE TDD below 1GHz. So the coexistence issue between Digital Terrestrial Television Broadcast (DTTB) and LTE TDD in Digital Dividend Spectrum is important in the spectrum plan [1]. In this paper, the interference from DTTB to LTE TDD is analyzed using deterministic analysis method and Monte Carlo simulation based on the digital TV standard of China. The results show that the uplink of LTE TDD is interfered more seriously. The effect of increasing protecting distance is not significant if protection distance is already large. The coexistence of the two systems in adjacent channels is possible if reasonable measures are taken in the network plan and spectrum plan.","PeriodicalId":348778,"journal":{"name":"2010 2nd IEEE InternationalConference on Network Infrastructure and Digital Content","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122160322","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}

Running an application program in a distributed fashion on an asymmetric memory architecture effectively is a challenging task. In this paper, we propose a novel load balancing technique for multi-core systems with asymmetric memory architectures. The proposed method uses probabilistic information on the expected execution time of the child processes for each parent process. Also, to maximize the load balancing effect with low cost, the proposed method groups processes, and treats each group as a load balancing unit. The trade-off between load balancing effect of each load balancing unit and the cost is taken into account. To show the effectiveness of this paper, we present test cases in which the proposed method show better performance than that of existing load balancing methods.","PeriodicalId":348778,"journal":{"name":"2010 2nd IEEE InternationalConference on Network Infrastructure and Digital Content","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133962615","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}
