This paper resent a data collection method of using mobile sink and static sink together against “thermal region” in wireless sensor network. The mobile sink visits the remote-cluster and communicates with the head node directly, thus reducing both the energy cost of multi-hop transmission in long distance and the frequency of data forwarding in clusters near the static sink. Simulation results showed that the added mobile sink extended the network lifetime and expanded the capacity of network.
