Abstract: Crowd sensing networks achieve large-scale sensing by using the existing sensing equipment of users as well as the deployed communication networks.Hence,it can efficiently address the critical problem of high cost of large scale network.However,during the process of task transfer and allocation for mobile users,group collusion as well as task copy and forwarding may cause serious threats for specific users.Aiming at this problem,based on crowd sensing network,this paper proposes a secure task distribution technique,whose main idea is to apply d-choice method in balls-into-bins theory into task allocation process and achieve load balancing for all users while the established threshold strategy ensures the security of user tasks.Simulation results show that,compared with the random task allocation technology,the proposed technology is able to balance the task load more efficiently,thus ensuring task safety.

摘要: 群智感知网络利用广大用户现有的感知设备和已部署的通信网络可实现大规模的感知,能够解决当前大规模感知网络成本较高的问题。然而移动用户在任务传输和分配过程中,群体合谋以及任务拷贝转发都会对特定用户任务的安全造成威胁。针对这一问题,基于群智感知网络,提出一种任务安全分发技术,通过将球箱理论中的d-choice方法应用到任务分配过程中,在实现全体用户负载均衡的同时,根据制定的阈值策略,保证用户任务的安全性。仿真结果表明,相比随机任务分配技术,所提出的技术能够更有效地均衡任务负载,从而保证任务安全。
