Due to the attenuation of Global Positioning System (GPS) signals in Indoor applications, alternative methods have been proposed to refine location estimates. In search of practical methods, researchers have considered the use of currently deployed 802.11 networks as the basis of positioning, adopting Received Signal Strength Indicator (RSSI) as the standard distance measure. However, attempts at accurate localization have failed due to reliance on heavily distorted power measurements acquired on saturated 2.4 and increasingly crowded 5 GHz channels. In this paper, A Dual Source-Observation Weighted Localization method is proposed as a solution to the Wi-Fi positioning problem, estimating user position through Tikhonov Regularization Cost Functional Minimization. This novel solution combines a) Weighted Kernel Ridge Regression (WKRR), and b) Weighted Radial Basis Function (RBF) Kernels to develop an algorithm which increases estimation accuracy by up to 1/4 meter compared to the current leading localization technology, Weighted K-Nearest Neighbors (WKNN), and substantially reduces error variance, due to the dual Empirical Loss, Complexity objective.","PeriodicalId":199195,"journal":{"name":"2014 Wireless Telecommunications Symposium","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124004011","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 network consists of two transceivers end nodes and N parallel amplify-and-forward (AF) relay nodes, where noise at the AF relay nodes may be correlated due to common interference or propagation through multiple hops. This paper assumes a practical scenario with correlated relay noises in contrast to the majority of the related work that assumes independent relays noise. Our objective is to maximize the worst signal-to-noise power ratio (SNR) of the two end nodes under individual relay power constraints and total relay power constraint in order to improve the users fairness for the two end nodes. This relay beamforming design is a non-convex problem taking the form of max-min optimization which could be solved by decomposing it into a series of solvable sub-problems using bisection search. Semi-definite relaxation problem (SDR) is used for the reformulation of the problem. The effect of the noise correlation on the beamformer design is analyzed for two cases, i.e., the first case when a complete knowledge of the correlation structure, represented by the relay noise covariance matrix (K), is available to the relay and the second one when no knowledge is available to the relay. Simulation results show performance improvement in terms of users fairness in comparison with un-optimized AF relaying in both cases. The obtained result indicates that the knowledge of the correlation structure increases the system performance w.r.t the case where no knowledge is available.","PeriodicalId":199195,"journal":{"name":"2014 Wireless Telecommunications Symposium","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117059618","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 routing protocol is one of the key components of WSNs and its features impact network performance significantly. We present an efficient Multi-Parent Hierarchical (MPH) routing protocol for wireless sensor networks; its main goal is to achieve reliable delivery of data in a single sink scenario while keeping low overhead, reduced latency and low energy consumption. The main features of MPH are self-configuration, hierarchical topology, persistence according to link quality, and source routing from sink to nodes. Network performance simulations of the MPH routing protocol are carried out and compared with two popular protocols, AODV, DSR and with the well-known algorithm ZTR (Zigbee Tree Routing). Results show that for the single sink scenario, the MPH protocol has an energy saving of 35% against AODV and DSR protocols and 8% compared with ZTR. MPH has 27% less overhead compared with AODV and DSR. And MPH presents a 10% increase in packet delivery compared with AODV, DSR and ZTR. Finally, we present a real WSN built based on the MPH protocol, which works satisfactorily, providing an experimental demonstration of the capabilities of the protocol.","PeriodicalId":199195,"journal":{"name":"2014 Wireless Telecommunications Symposium","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125019112","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}
