Underlying connectivity mechanisms for multi-radio wireless sensor and actuator networks

This work proposes mechanisms enabling connectivity in multi-radio wireless sensor and actuator networks, namely: network discovery, interface/channel switching, and connection-loss recovery. The considered mechanisms are optimized with the aim to maximize the availability of system services (minimize network down-time) and achieve an increased overall robustness. The proposed approach offers dynamicity and adaptability to the constantly changing operating conditions of the different radio interfaces as well as to application-level requirements, and ensures self-organizing and autonomous operations.
