The constant progress in technology gives the opportunity to obtain efficient, in terms of cost and accuracy, localization services, and likewise it increases the number of challenges to be considered. The main problems related to the localization of mobile devices concern with the heterogeneity of visited environments and interested hardware platforms, the energy and computational constraints imposed by the devices and the choice of appropriate tracking technologies. The most important goal in the localization research area is to provide a very accurate positioning service, regardless the surrounding environment. For my PhD research I propose an innovative system for ubiquitous localization which does not rely on backend servers (each node performs a self-localization) and whose reference platform is a new generation mobile phone. This system exploits the sensors embedded on such devices to perform positioning and it is further assisted by opportunistic exchange of information among neighboring nodes. By means of this system, a node is able to classify its movements by continuously refining a self-movement-model (machine learning techniques), thus assisting the localization procedure itself. The purpose of this document is to briefly describe the state of the art in localization, and to outline my planned PhD research.","PeriodicalId":384628,"journal":{"name":"2010 IEEE International Symposium on \"A World of Wireless, Mobile and Multimedia Networks\" (WoWMoM)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126132734","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}

In this context, wireless network simulators play a key role in the design, development and testing of new wireless sensor networks applications and protocols. Most of the currently available wireless sensor network simulators work well for small to medium sized networks yet fail to scale to really large networks, mainly due to their single desktop machine architecture and its limited resources. In this paper, we present XS-WSNet, a wireless sensor network simulator that is designed with extreme scalability as a prime objective. First, we distribute the simulated wireless sensor network nodes on a variety of actual machines that communicate through a wired network. A large-scale simulation is then emulated by several smaller scale simulations that run concurrently and collaboratively. As smaller instances of simulations running on different machines usually induce asynchrony and non-determinism in the whole system, we also propose a distributed synchronization protocol, responsible for simulation accuracy in some simulation models. Our implementation (both asynchronized and synchronized versions) of XS-WSNet is fully evaluated in various contexts using a scalable benchmark application. Against its single machine version, the distributed simulator provides sensible matching results, exhibits both scale-up and speed-up of the simulation, and performs with linear slowdown with up to ten million simulated nodes.","PeriodicalId":384628,"journal":{"name":"2010 IEEE International Symposium on \"A World of Wireless, Mobile and Multimedia Networks\" (WoWMoM)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116399988","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}

In this paper we investigate how specific PHY-layer operations, designed to mitigate the effect of interference, can cause the radio-receiver circuitry to over-estimate the channel occupation status, thus unnecessarily limiting the overall spatial reuse or impeding the synchronization to incoming frames. We individuated the root of this problem in the surprising effectiveness of the overall packet detection procedure of WLAN PHY, which allows for the demodulation of strongly attenuated 802.11 frames. The transmit spectrum mask for the IEEE 802.11 standard allows limited power leakage over adjacent channels. Such a low power signal from adjacent channels nowadays can be correctly recognized by recent OFDM/CCK receive circuitry, which has an important impact on WLAN performance. A receiver may miss the reception of packets destined to it, whenever a frame capture of a transmission on a partially overlapping channel occurs. A similar effect occurs in the transmit phase. In carrier sense mode, the OFDM/CCK receiver of the WLAN device is capable of synchronizing to the preamble of low SNR signals, thus unnecessarily deferring the channel access in case of transmissions on partially overlapping channels.","PeriodicalId":384628,"journal":{"name":"2010 IEEE International Symposium on \"A World of Wireless, Mobile and Multimedia Networks\" (WoWMoM)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122794598","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 basic operation in WSNs is the systematic gathering and transmission of sensed data to a base station for further processing. During data gathering, the amount of data can be large sometimes, due to redundant data combined from different sensing nodes in the neighborhood. Thus the data gathered need to be processed before being transmitted, in order to detect and remove redundancy, which can impact the communication traffic and energy consumption of the network in a negative way. In this paper, we propose an algorithm to measure similarity between the data collected toward the base station(relative to a specific event monitoring), so that an aggregator sensor sends a minimum amount of information to the base station in a way that the latter can deduce the source information of sensing neighbors nodes. Further, our experimental results demonstrate that the communication traffic and the number of bits transmitted can be minimized while preserving accuracy on the base station estimations.","PeriodicalId":384628,"journal":{"name":"2010 IEEE International Symposium on \"A World of Wireless, Mobile and Multimedia Networks\" (WoWMoM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126265938","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}

Specifically we propose a distributed scheme that establishes access control while protecting the privacy of a user in both sporadic and continuous LBS queries. Our solution employs a hybrid network architecture where LBS users: (a) are able to communicate with an LBS provider through a network (e.g., cellular) operator, and (b) they are also able to create wireless ad-hoc networks with other peers in order to obtain privacy against an adversary that performs traffic analysis. Our threat model considers the network operator, the LBS provider and other peers, as potential privacy adversaries. For historical privacy we adopt the generic approach of using multiple pseudonyms that are changed frequently. In order to establish untraceability against traffic analysis attacks, a message is not sent directly to the cellular operator, but it is distributed among mobile neighbors who act like mixes and re-encrypt a message before sending it to the LBS provider via the cellular operator. As an extension, we also discuss how to aggregate independent data from different mobile peers before sending them to the LBS provider. This approach may be suitable in applications where aggregate location data are useful (e.g., traffic monitoring and control)","PeriodicalId":384628,"journal":{"name":"2010 IEEE International Symposium on \"A World of Wireless, Mobile and Multimedia Networks\" (WoWMoM)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132920351","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}
