Experimental Evaluation of a Distributed Sensor Network Applying Source Node Grouping

In conventional sensor networks, information sensed by distributed sensor nodes is collected to a sink node, and applications are executed based on this information. However, when actuator nodes in a field execute the applications, the sink node does not have to collect all the sensing information, but each actuator node collects the information required for its application. We aim to collect the required information to each actuator node, and generate a group whose members are source sensor nodes involved by each actuator node. We propose a protocol to efficiently collect sensing information of grouped source nodes. Furthermore, we experimentally demonstrate that actuator nodes can collect the information and that the proposed protocol can decrease the number of packets transmitted in the network.
