In certain event driven sensor-actor networks, event locations should be identified precisely. When an event occurs, all the nodes in that area communicate with the actor which increases collision and packet loss. Event nodes should be identified in such a way to reduce the number of redundant data transmissions. Existing methods lead to a large increase in end-to-end latency, which affects the efficiency of the sensor-actor network. We propose a novel pattern based routing protocol for identifying the event nodes in sensor-actor networks that require minimum latency. Pattern based protocol activates the nodes only when patterns are detected in order to avoid unwanted message relay. If any node senses a pattern, data is transmitted to the corresponding actor through the event nodes. Transmitting only essential information in the form of patterns reduces the number of collisions and improves the latency. The proposed 'Pattern Based Routing' (PBR) for event driven sensor-actor networks is used to reduce the message size by using patterns and improve the packet delivery ratio for efficient identification of event nodes. Simulation results show that the proposed PBR reduces the latency 60% less than AODV with higher packet delivery ratio.
