This is due to the incidence of Non-Line-of-Sight (NLOS) distance measurements between the anchors and an unlocalized node. While a large corpus of research work dealt with the scenario where the NLOS distances form a minority of the total distances to anchors, there has been not much research done to handle the situation where a majority or even all distance measurements to anchors are NLOS in nature. In our previous work, we showed that using localizers in a cluttered environment can improve the localization accuracy of a target node even when all the distance measurements are NLOS. Instead of NLOS bias, these techniques suffer residual multi-hop error, which is caused due to the distance overestimate when a multi-hop chain is used instead of the straight-line distance. In this paper, we analyze the effect of clutter topology on the multi-hop error. We use machine learning techniques to estimate the aggregate forms of the multi-hop error for a given clutter topology when only characteristic features of the clutter topology are provided.","PeriodicalId":381489,"journal":{"name":"2014 12th International Symposium on Modeling and Optimization in Mobile, Ad Hoc, and Wireless Networks (WiOpt)","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127040629","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 such example scenario is: primary customers demand certain Quality of Service (QoS) and the idea is to utilize the surplus server capacity to serve a secondary class of customers. We use achievable region approach for this. Towards this, we consider a two queue polling system and study its `approximate achievable region' using a new class of delay priority kind of schedulers. We obtain this approximate region, via a limit polling system with fluid queues. The approximation is accurate in the limit when the arrival rates and the service rates converge towards infinity while maintaining the load factor and the ratio of arrival rates fixed. We show that the set of proposed schedulers and the exhaustive schedulers form a complete class: every point in the region is achieved by one of those schedulers. It is well known that exhaustive service policy optimizes system performances like unfinished work. In this paper, we show that it is also optimal from the perspective of individual queues. We further pose two constrained optimization problems: a) admission control, wherein the arrival rates of secondary customers is optimally designed; b) maximizing the revenue considering the losses when secondary arrival rate is fixed. We finally show that exhaustive service discipline at each queue turns out to be optimal.","PeriodicalId":381489,"journal":{"name":"2014 12th International Symposium on Modeling and Optimization in Mobile, Ad Hoc, and Wireless Networks (WiOpt)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130235225","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}

Coverage analysis remains as one of the essential topics on which mobile operators still need innovation in terms of performance and cost. Manual coverage analysis is an inefficient and costly task. Radio Environment Maps (REMs) is an efficient coverage analysis solution for present-day cellular networks. REM concept consists of spatially interpolating geo-located measurements to build the whole coverage map using a spatial interpolation technique originating from geo-statistics. Kriging is such a powerful technique which results in high performance in terms of prediction quality. However, this method is costly in terms of computational complexity especially for large datasets: computational complexity of Kriging is O(n3) where n is the number of measurements. This paper proposes the application of a variant of Kriging, Fixed Rank Kriging (FRK), to coverage analysis in order to reduce the computational complexity of the spatial interpolation while keeping an acceptable prediction error.","PeriodicalId":381489,"journal":{"name":"2014 12th International Symposium on Modeling and Optimization in Mobile, Ad Hoc, and Wireless Networks (WiOpt)","volume":"27 3-4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133453495","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}
