Many distributed applications require cooperating to fuse their data in those WSNs in real time. Some of these WSNs allow interacting with Publishers and Subscribers (Ps/Ss) sensors. But, there exist little research works on development of causal ordering based on virtual synchronous group membership of these P/S systems, one of mandatory properties for this kind of application fields. In this paper, the authors propose a novel approach based on gossip protocols and virtual synchronous group membership, guaranteeing the causal message ordering in those WSNs.
