The major issue in TOA-based localization schemes is that the presence of error due to non-line-of-site (NLOS) propagation in the range measurements introduces a lot of errors in location estimation. Thus we have focused on those TOA-based localization schemes that can mitigate the effect of NLOS errors to provide reasonable location accuracy. Another major issue in TOA-based localization is the computational complexity incurred by solving the non-linear equations associated with the location estimation. Thus, among the various TOA-based localization schemes that work in NLOS environment, we have chosen two-step least square (LS) method for estimation of location of a mobile user in WLAN environment. To the best of our knowledge, no such real evaluation of two-step LS method does exist in literature. In this paper, we have proposed a novel technique for estimation of round trip time (RTT) between the Base Station (BS) and the Mobile Station (MS) of Internet Control Message Protocol (ICMP) packet in order to avoid the requirement for exact synchronization between the MS and the BS. Our proposed technique also shows a statistical post-processing step to reduce the errors incorporated into TOA measurements. Moreover, in this paper we have compared the performance of two-step LS method in theoretical environment with that in WLAN environment.","PeriodicalId":445751,"journal":{"name":"2011 IEEE 5th International Conference on Internet Multimedia Systems Architecture and Application","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121444873","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}

Seated in one place today, man can do just about anything with his portable palm size gadgets. But as the sizes of gadgets shrunk, iniquity and espionage magnified to monstrosity. Scientists over the years while devised techniques to shrink gadgets, also cerebrated algorithms to check the infraction. This paper proposes yet another method using the pixel indicator technology to increase the capacity of the message carrier; i.e. cover object. The pixel indicator is used to decide where the clandestine information has been embedded and to which colour plane of the cover image. Later how many clandestine data would be embedded on the chosen plane of the pixels is decided by the MSB of all the three planes. This proposed method also includes additional integrity check mechanism with improved randomness and hence the security. Simulation tests & complexity analysis were performed to evaluate the dexterity and complexity of the proposed algorithm.","PeriodicalId":445751,"journal":{"name":"2011 IEEE 5th International Conference on Internet Multimedia Systems Architecture and Application","volume":"356 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131762321","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 evolution of the telecom networks have also driven the evolution of Service Delivery Platforms (SDP) from in-flexible single-box solution to a flexible, modular SOA governed SDP to cater the ever changing business needs of the Telcos. The fourth generation SDP is taking shape around cloud computing with an expectation to significantly reduce OPEX and CAPEX, and boost the revenue. But this is not happening because in the current scenario where SDPs are hosted on private cloud in Telcos' own premises prohibit sharing and reuse. So Telcos have started transitioning to a hosted model in which VAS applications are hosted in SDP vendor's premises in public cloud. Hosting telecom services in public cloud has its unique challenges, and one of the most important is to provide a multi-tenant telecom application to all Telcos, where each tenant sees an isolated view of the application with his own set of customized features. In this paper we have identified the factors that are stopping us from introducing true customized multi-tenancy in telecom apps and proposed a solution to this problem. We have presented a variant of cloud's SaaS layer called Telecom-SaaS (TSaaS) for telecom public cloud, which introduces a TSaaS-engine to drive the multi-tenancy for carrier grade telecom applications outside the actual business logic. New business models that can evolve around this new architecture are also identified. We have also highlighted the associated risks to watch out for.","PeriodicalId":445751,"journal":{"name":"2011 IEEE 5th International Conference on Internet Multimedia Systems Architecture and Application","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134332727","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 system suggests an “anytime anywhere” health monitoring mechanism via an application providing rich contextual visualization of health data through easy-to-use interfaces. Using SESGARH, patients with chronic illnesses can send disease symptoms and other critical health information to a physician, who can analyze this data remotely and prescribe e-prescriptions. SESGARH can significantly minimize time taken for transmission of healthcare data from patient to physician and vice-versa, and improve the reach and quality of healthcare services. Proposed system is based on the ISO/IEEE11073 (X73) family of standards supporting high quality medical sensors, as well as wireless transport (e.g. Bluetooth, WiFi, Zigbee) for access to faster and reliable communication network resources. JSON, a lightweight text-based open standard, is used to represent the data, which is interchanged between SESGARH and remote server over HTTP. We have successfully implemented and demonstrated SESGARH — using ECG body sensors, a Smart-phone device acting as a mobile gateway running the application, and a remote server to which the physician is connected.","PeriodicalId":445751,"journal":{"name":"2011 IEEE 5th International Conference on Internet Multimedia Systems Architecture and Application","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127303450","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}
