1. A clustering based data aggregation method for multi-target tracking in a sensor network, the method comprising:

  • selecting, by a first sensor node, a cluster head from a cluster in a backbone network based on a hop count to a backbone node for relaying target sensing data from the first sensor node to a sink node; and

    transmitting the target sensing data to the cluster head such that the cluster head aggregates the target sensing data of the first sensor node and target sensing data of other sensor nodes included in the cluster and transmits the aggregated target sensing data to the backbone node.
