Wireless sensor networks are increasingly used for monitoring applications. It is envisioned that a single network deployment will have to handle numerous applications, possibly with different QoS requirements. Multi-stack architectures address this issue, as it allows different combinations of MAC and routing protocols to coexist in the network: each combination can be used to guarantee a given QoS. In this paper, we propose a queue-exchange mechanism that reduces the delay of multi-stack architectures, and facilitates its inherent dimensioning problem. The queue-exchange mechanism allows frames to be sent with any combination of protocols, and thus improves the global throughput in the network. We quantify through simulations the benefits of our mechanism on random topologies, according to multiple performance metrics.
