PAAR: A routing protocol for context-aware services in wireless sensor-actuator networks

DSSR is one of protocols for context-aware services in SANETs. By using user contexts, only the sensors that are relevant to a device's operating pattern transmit messages to the actuator. However there are some drawbacks for SANETs. To address DSSR problems, a routing protocol PAAR is proposed. Simulation studies show that our approach can lead to significant reductions in routing traffic and increases in service duration compared with DSSR. PAAR with 23 sensors for 11,520 minutes can reduce 10% of the number of communications compared with DSSR. This can also increase service duration by 50% on average.
