Energy-Effective and Secure Data Transfer Scheme for Mobile Nodes in Smart City Applications

Mobile nodes are deployed at different locations in the smart city to collect meaningful information so captured data can be used as an input in different smart city applications for society benefits. However, data is transferred through a public communication channel and thus, it is important to achieve specific security level to protect from malicious users in the network. There are various data transmission methods for mobile environments, but they are vulnerable against fundamental security attacks and the performance results are not effective for the mobile ad-hoc network. In this paper, we identify some security issues in Islam et al.’s scheme. To address found issues and improve the security and efficiency, we propose an energy-efficient and secure communication scheme for mobile node applications, achieving user identity privacy. We do security evaluations of the proposed protocol to confirm its strengths against various attacks. Further, we discuss performance analysis (for execution cost, energy consumption, communication overhead, and storage cost) for the suggested data transmission method and then, do the comparison with other relevant communication mechanisms.
