Since the data received at the sink node to collect from many nodes the data traffic is considered. In this paper, we present DMAC (Data Gathering Medium Access Control) protocol, an efficient energy and low delay time for gathering data on WSNs (Wireless Sensor Networks) based on the data gathering tree structure. DMAC protocol is proposed to solve the interruption problem that suffers from a data forwarding when using MAC protocol and allows continuous packet forwarding by proving the suitable sleep schedule of a node that depends upon its depth on the tree. Based on the protocol, we adjust the duty cycles adaptively according to the traffic load in the network. Besides, we apply a data prediction mechanism for proposed scheme and use of More-To-Send (MTS) packets in order to avoid problems pertaining to channel contention and collisions. As a result, DMAC protocol improves energy consumption and delay time of networks clearly while ensuring high data reliability.","PeriodicalId":377853,"journal":{"name":"2014 IEEE Fifth International Conference on Communications and Electronics (ICCE)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116084598","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}

This factor, which depends on the multichannel speech presence probability (MC-SPP), helps significantly reduce background noise while suffers only a little speech distortion. In addition, we also propose to modify the minima controlled recursive averaging (MCRA) algorithm, by exploiting shorter time frames and slower statistic change in speech signals, which helps increase the computing speed with almost no degradation in the estimation quality of noise statistics. The performance of our algorithms are simulated and verified for various noise scenarios.","PeriodicalId":377853,"journal":{"name":"2014 IEEE Fifth International Conference on Communications and Electronics (ICCE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117075486","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 non-beacon nodes are represented by vectors including hop-counts information from themselves to all of the beacons. Based on the information, the beacons give local estimates on locations of non-beacon nodes by Kernel method, by which each non-beacon node determines its final position using majority vote rule on the estimates.

The piezoelectric sensor signal is utilized for biasing a cross-coupled differential rectifier chain to an operating point where the RF signal energy can be efficiently harvested even if its amplitude is below the threshold voltage of the cross-coupled rectifier transistors. An adaptive biasing circuit ensures that the optimal operating point of the rectifier/multiplier can be tracked across different levels of input RF signal. The measurement results obtained from a 7-stage hybrid voltage-multiplier operating on 10 MHz RF signals show that the proposed technique can yield significant improvements in power conversion efficiency for low input power as compared to a conventional cross-coupled voltage multiplier circuit on the same die.","PeriodicalId":377853,"journal":{"name":"2014 IEEE Fifth International Conference on Communications and Electronics (ICCE)","volume":"190 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123358694","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 WSNs' unique characteristics, especially their high distributed nature and limited resources pose significant challenges in developing algorithms for the application. Hence, the design of target tracking system needs to deal with several factors such as energy consumption, processing capability of sensor node, tracking accuracy, and also real time property. In this paper, we present a framework for a collaborative target tracking system. Our efforts in this research also focus on developing a duty cycle XT-MAC protocol associated with EMRP routing algorithm to enhance system performance in the aspects of end-to-end delay, and energy efficiency while maintaining the tracking accuracy. The simulation results show that our method significantly improved the above parameters.","PeriodicalId":377853,"journal":{"name":"2014 IEEE Fifth International Conference on Communications and Electronics (ICCE)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125220149","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}

High birefringence property of the device incorporated with butterfly form allows to shortening the size. The polarization extinction ratio is smaller than 20 dB, and the excess loss is not excess 0.6 dB for both polarization modes. The splitter also has a relaxed fabrication tolerance.
