Abstract
Mobile edge computing (MEC) sinks computing power to the edge of networks and integrate mobile access networks and Internet services in 5G and beyond. With the continuous development of services, it is extremely important of privacy protection in a heterogeneous MEC system for multi- server collaboration. However, most of the existing schemes only consider the privacy of users or services other than privacy of network topology. For the purpose of topology privacy protection, this paper employs blockchain to construct heterogeneous MEC systems and adopts accommodative bloom filter as a carrier for multi-domain collaborative routing consensus without exposing topology privacy. Blockchain is used to implement multiplex mutual trust networking and collaborative routing verification through the membership service and consensus mechanism. Experiments are conducted to evaluate the feasibility and performances of our scheme. The results indicate that the proposed scheme can highly improve the credibility and efficiency of MEC collaboration.
