A novel distributed ranking method based on activator-inhibitor model for multicellular array architecture

This paper presents a novel distributed ranking method based on activator-inhibitor model theory for multicellular array architecture. Cell ranking in multicellular array means that sequence number 1, 2, ···, n have to be assigned to the different cells. This method has two characteristics: 1) it´s an active cell ranking and sequence number maintaining method compared to existing passive cell sequence number maintaining methods in multicellular array architectures; 2) it doesn´t need initial value to rank and maintain cell sequence numbers, which is different from ordinary distributed ranking methods based on initial values. This method imitates the active sequence maintain mechanism in organisms to eliminate the single-point-of-failure properties of existing cell sequence number maintaining methods. Fault-injection experiments show our method has better robustness than existing methods.
