...nto two major categories: those that provide anonymity and those that introduce obfuscation. Location privacy can be provided via the frequent changing of pseudonyms (Marco, 2003; Huang et al., 2005; =-=Freudiger et al., 2009-=-; Jiang et al., 2007) to make it difficult for adversaries to estimate a user’s trajectory. The system first defines several special regions named ‘mix zones’. In a mix zone, a number of nodes will en...

...trategies of local adversaries and mobile users with a limited budget. This paper is part of the trend of blending game theory with security to predict the strategies of the rational parties involved =-=[1, 6, 7, 12, 14, 19, 27, 31]-=-. This paper is organized as follows. In Section 2, we present the system and threat models. We also describe how mix zones provide location privacy. In 2Section 3, we introduce the game-theoretic fr...

Combining game theory with epidemic models, such as the susceptible-infected-removed (SIR) model [6], is a practical approach to studying strategic behavior for large populations of agents. T...

...nformation. Li et al. [11] propose a method to prevent an adversary to track the location of users, by allowing users to change their pseudonyms. Through a game theoretical analysis, Freudiger et al. =-=[12]-=- suggest some improvements on this protocol by Li et al. [11]. Our proposed solution has its focus on location privacy, it can be extended to satisfy more properties like user anonymity. Papers on ver...

Selfish behaviour of the nodes in mix zones has also been considered recently =-=[7]-=-, as well as how pseudonyms aging affects privacy [8]. An idea similar to the one of mix zone is path confusion [14,15]—pseudonyms are exchanged between nodes that have 328 L. Marconi et al. paths clo...

...h quality of movie loading solutions. Thus the problem is that the server should take over the substantial processing expense, as the number of customers increases. have suggested to make customized brilliant providers for maintenance cellular customers, e.g., Cloudlet and Status. This is because, in the reasoning, many broker instances (or threads) can be maintained dynamically and efficiently based on the time-varying customer demands. Lately online community solutions (SNSs) have been popular. There have been suggestions to enhance the high high quality of material delivery using SNSs [23] [24]. In SNSs, customers may share, comment or re-post video clips among buddies and associates in the same team, which implies a customer may observe video clips clip that her buddies have recommended (e.g. [24]). Users in SNSs can also follow famous and accepted customers based on their interests (e.g., an official twitter or facebook account that shares the latest pop music videos), which is likely to be watched by its followers. In this regard, we are further inspired to manipulate the relationship among cellular customers from their SNS behavior to be able to prefetch in advance the beginning...
