Abstract Aiming at the access problem of WSN(wireless sensor network)ON (opportunistic network), a cluster head election method based on game theory (CEGT) was proposed by the ON bundle protocol. CEGT could effectively improve the network connectivity under the special access environment of apron network. In the WSN node clustering stage, the game model was established by measuring the multiple social attributes of node to elect the cluster head more energyefficiently. Under the bundle protocol, the effectiveness of the communication between cluster head and mobile agent (Magent) was the access quality, which determined the quality of the network. The simulation results show that CEGT control method can reasonably elect the cluster head and reduce the node mortality to 57% for extending the network life cycle. Under the bundle protocol, when the numbers of nodes and buffer size are different, compared with non Magent boundary, the encounter opportunities by Magent can improve the delivery rate of cluster heads and achieve efficient ON access.
