In existing research, tremendous efforts have been brought to obfuscation techniques and developing new anonymity to preserve the location privacy. However, these techniques may either sacrifice the service accuracy or rely on a trusted third party. To deal with this, in this paper, we propose a decentralized data forwarding...
Security, communication delay, and delivery ratio are essential design issues in urban sensing networks. To address these three issues concurrently, we propose a novel delay-aware privacy-preserving (DAPP) transmission scheme based on a combination of two-phase forwarding and secret sharing. In DAPP, the collected data are first split into pieces, and then, each piece is relayed to an application...
