Abstract: Mobicast，a novel multicast routing protocol，is very suitable for Wireless Sensor Tracing Networks（WSTNs）.But some corresponding improvements will also be required for the multi-objective monitor.A self-perceive clustering mechanism scheme Mobicast-based，which can adjust the clustering strategy dynamically according to the networks topology and targets’ situation to prevent from the overlap and interference between clusters，is presented for maximizing the network performance and multicast efficiency.The main contributions of the approach are summarized as follows：⑴ determining the number and state of monitoring objectives，and selecting the clustering strategy through self-perception clustering algorithm；⑵ evaluating dynamically the current topology and capability of nodes in order to update the clustering strategy.The simulation results indicate that this scheme can monitor the multi-objective more accurately compared to their real route.
