wChain: A Fast Fault-Tolerant Blockchain Protocol for Multihop Wireless Networks
This paper presents , a blockchain protocol specifically
designed for multihop wireless networks that deeply integrates wireless
communication properties and blockchain technologies under the realistic SINR
model. We adopt a hierarchical spanner as the communication backbone to address
medium contention and achieve fast data aggregation within slots where is the network size and refers to the
ratio of the maximum distance to the minimum distance between any two nodes.
Besides, employs data aggregation and reaggregation, and node
recovery mechanisms to ensure efficiency, fault tolerance, persistence, and
liveness. The worst-case runtime of is upper bounded by
, where is the upper
bound of the number of faulty nodes. To validate our design, we conduct both
theoretical analysis and simulation studies, and the results only demonstrate
the nice properties of , but also point to a vast new space
for the exploration of blockchain protocols in wireless networks.Comment: 11 pages, 3 figures; preprin
