Node misbehavior due to malicious attacks can impair the overall functioning of the system. Existing approaches mainly rely on cryptography to ensure data authentication and integrity. These approaches only address part of the problem of security in sensor networks. However, cryptography is not sufficient to prevent the attacks in which some of the nodes are overtaken and compromised by a malicious user. Recently, the use of reputation systems has shown positive results as a self-policing mechanism in ad-hoc networks. This scheme can aid in decreasing vulnerabilities which are not solved by cryptography. We look at how a distributed reputation scheme can benefit the object tracking application in sensor networks. Tracking multiple objects is one of the most important applications of the sensor network. In our setup, nodes detect misbehavior locally from observations, and assign a reputation to each of their neighbors. These reputations are used to weight node readings appropriately when performing object tracking. Over time, data from malicious nodes will not be included in the track formation process. We evaluate the reputation system experimentally and demonstrate how it improves object tracking in the presence of malicious nodes","PeriodicalId":440604,"journal":{"name":"2006 Third Annual International Conference on Mobile and Ubiquitous Systems: Networking & Services","volume":"347 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115893875","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 prime motivation is to balance the inherent trade-off between the energy wasted in collisions and the energy expended by collision avoidance handshake mechanisms. Towards this objective, the study goes through two phases. First, we explore the space of MAC modes subject to the constraint that different access schemes can inter-operate. Accordingly, we limit our attention to modes within the non-slotted random access paradigm. Second, we analyze, with the aid of detailed network simulations, the energy performance trade-offs of four variations of the CSMA/CA access scheme. Finally, we shed some light on the problem of dynamically switching between different modes depending on the network loading conditions and application QoS requirements. Initial results reveal interesting observations related to the energy/delivery contribution of channel reservation and single-hop acknowledgment packets under a wide variety of temporal network loads","PeriodicalId":440604,"journal":{"name":"2006 Third Annual International Conference on Mobile and Ubiquitous Systems: Networking & Services","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124340666","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}
