Abstract
A node in an ad-hoc network includes a memory unit storing a concatenated counter value including an erasure counter value and a transmission counter value for the node; and a processor configured to: add one to the transmission counter value, when the node transmits data to another node in the ad-hoc network; transmit to the other node, the data and the updated concatenated counter value; detect erasure of the concatenated counter value in the memory unit; distribute in the ad-hoc network and upon detecting the erasure, an acquisition request for the erasure counter value; receive the erasure counter value consequent to the acquisition request; generate the concatenated counter value to include the received erasure counter value plus one and the transmission counter value after the erasure and indicating the number of transmissions as zero due to the erasure; and archive to the memory unit, the generated concatenated counter value.
