Many rate adaptation algorithms proposed, utilizes the multi data rate, primarily according to the current channel quality. Most algorithms do not consider congestion around the network and proper determinant to identify it. In multi rate Ad hoc network, due to mismatched link rate, the node interface queues get overloaded. Thus causing congestion, which consequently result in packet loss, further reducing effective throughput. In this paper, we propose a novel Cross layer QoS aware Multi Rate routing protocol (CQMR) based on nodes queuing load and link state. CQMR focuses on cross-layer interactions between PHY, MAC and Network layer to utilize these multi-rate supports from 802.11b. CQMR algorithm chooses the optimal path with effective data rate and through a less congested network, which is compatible with existing 802.11 implementations. We have implemented CQMR in the NS-2 simulator and conducted extensive simulation studies over network diversity. Our analysis shows that CQMR protocol significantly increases the network performance in the packet delivery ratio and throughput.","PeriodicalId":318875,"journal":{"name":"2015 International Conference on Signal Processing and Communication (ICSC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130446426","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 proposed structure consists of two inner hexagonal layers and outer three circular layers. The inner hexagonal layers consist of air holes each of diameter d1. Two circular layers surrounding the hexagonal layers have air holes of diameter d2 while the outer most circular layer has air holes of diameter d3. The proposed structure is shown to possess an optimum mode profile. The effective refractive index of the cladding depends on the air-fill fraction of the fiber. Refractive index decreases with increasing air-fill fraction for the same wavelength. It is shown that the negative dispersion coefficient can be controlled by the pitch Λ and the diameter of air holes. Also shown is the linear relation of Birefringence with bit rate. The corresponding graphs of all the parameters are evaluated and plotted. The proposed structure is simulated using the commercial Rsoft software.","PeriodicalId":318875,"journal":{"name":"2015 International Conference on Signal Processing and Communication (ICSC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130446677","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}

One of the properties of snow is the amount of water that results from melting of snow-pack. The amount of water in snow is known as Snow Water Equivalent (SWE). SWE is useful in many areas like estimation of water availability from snow melt, assessment of snow-pack density etc. The information of density is used to estimate the strength of snow-pack. The knowledge of strength can be useful for the prediction of avalanche prone areas. There are several techniques available for the measurement of SWE. The techniques for SWE measurement are generally invasive and time consuming in nature. Researchers have developed noninvasive acoustic techniques for SWE measurement. But lot of assumptions are taken in these SWE measurement techniques, which results in inaccurate estimation of SWE. A new noninvasive acoustic technique based on use of very directional sound source and associated signal processing method is presented, in this paper. This new acoustic technique does not require calculation of reflection coefficients for SWE estimation.","PeriodicalId":318875,"journal":{"name":"2015 International Conference on Signal Processing and Communication (ICSC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115547288","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 performance of the circuit is enhanced using optimization algorithm with multiple constraints but it require the circuit performance be modeled with mathematical expression. In this paper we use EKV2.6 model parameters which is extracted and optimized on different bins of BSIM3v3 model on 0.18μ technology to design standard analog building blocks like single stage common source amplifier, differential amplifier and OTA using gm/lD ratio design methodology. Finally all the design are validated on HSPICE using BSIM3v3 MOSFET model with matching within limit of 10%. This capability of above work shows a complete procedure in the design for a standard specification of OTA.","PeriodicalId":318875,"journal":{"name":"2015 International Conference on Signal Processing and Communication (ICSC)","volume":"99 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126102594","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}
