In order to provide emergency services functionality over the Internet, several aspects like location determination, dial string configuration, location conveyance, routing to the appropriate public safety answering point (PSAP) and security aspects have to be considered. This paper discusses security threats for the IP-based emergency architecture concentrating on denial-of-service attacks against public safety answering points (PSAPs) by using faked calls that aim to exhaust limited PSAP resources, such as the emergency personnel. We illustrate a number of different approaches that have been mentioned in the past to tackle these threats, including location signing, location-by-reference and authenticated emergency calls.","PeriodicalId":356565,"journal":{"name":"2007 IEEE International Performance, Computing, and Communications Conference","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114301794","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}

Within this area, privacy-preserving association rule mining has received considerable attention, and most algorithms proposed in the literature have focused on the case when the database to be mined is distributed, usually horizontally or vertically. In this paper, we focus on the case when the database is distributed vertically, and propose an efficient multi-party protocol for evaluating item-sets that preserves the privacy of the individual parties. The proposed protocol is algebraic and recursive in nature, and is based on a recently proposed two-party protocol for the same problem. It is not only shown to be much faster than similar protocols, but also more secure. We also present a variant of the protocol that is resistant to collusion among parties.","PeriodicalId":356565,"journal":{"name":"2007 IEEE International Performance, Computing, and Communications Conference","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115373354","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}

However, for some applications such as emergency message dissemination in ad hoc networks, priority-ensured medium access is critical for timely message delivery. This paper proposes a new medium access control (MAC) scheme that provides priority-ensured medium access service for such applications in fully-distributed ad hoc networks. The basic idea of the scheme is to encode and deliver priority information by out-of-band pulses. The comprehensive simulation results in the paper show that the proposed MAC scheme is effective in serving emergency message dissemination in vehicular ad hoc networks.","PeriodicalId":356565,"journal":{"name":"2007 IEEE International Performance, Computing, and Communications Conference","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129924441","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 paper examines the relationships between disaster tolerant systems, information technology (IT) application availability and executive level management visibility necessary for successful system operations in the event of a catastrophic disaster; one which causes rapid, almost simultaneous, multiple points of failure in a system, as well as a single points of failure that escalate into wide catastrophic system failures. The technology, process and human resource challenges of traditional disaster recovery approaches to disaster preparedness are outlined. The risks of IT application downtime attributable to the increasing dependence on critical information technology applications operating in distributed and unbounded networks are explored. A general method for disaster tolerance is proposed which mitigates unplanned downtime through a disciplined approach of IT infrastructure design based on redundancy and distributed components with special attention given to the ability of executive level management to comprehend the value of uptime of an application and make appropriate capital investment. The importance of executive visibility into the system wide impact of downtime and the resultant effects on the costs of downtime of critical systems is explored.","PeriodicalId":356565,"journal":{"name":"2007 IEEE International Performance, Computing, and Communications Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125277566","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}

Since these actions can be taken at any spot within the monitored area, the actors should be carefully placed in order to provide maximal coverage. Moreover, the actors often coordinate among themselves in order to arbitrate tasks and thus inter-actor connectivity is usually a requirement. In this paper, we propose a distributed actor positioning algorithm that maximizes the coverage of actors without violating the connectivity requirement. The approach applies repelling forces between neighboring actors, similar to molecular particles in Physics, in order to spread them in the region. However, the movement of each actor is restricted in order to maintain the connectivity of the inter-actor network. The performance of the approach is validated through simulations.","PeriodicalId":356565,"journal":{"name":"2007 IEEE International Performance, Computing, and Communications Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129138925","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 present an optimized link state routing (OLSR)-based localization (ROULA) that satisfies the following key design requirements: (i) Independency from anchor nodes, (ii) robustness for non-convex network topology, and (iii) Compatibility with network protocol. ROULA is independent from anchor nodes and can obtain the correct node positions in non-convex network topology. In addition, ROULA is compatible with OLSR protocol, and it uses the inherent distance characteristic of multipoint relay (MPR) nodes. We reveal characteristics of MPR selection and the farthest 2-hop node selection used in ROULA, and describe how these node selections contribute to reducing the distance error for a localization scheme without ranging devices. We used a simulation to specify appropriate MPR_COVERAGE for ROULA, and give a comparative performance evaluation of ROULA for various scenarios including non-convex network topology and various deployment radii of anchor nodes. Our evaluation proves that ROULA is effective for localization in various network scenarios.","PeriodicalId":356565,"journal":{"name":"2007 IEEE International Performance, Computing, and Communications Conference","volume":"79 9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130691614","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}
