Wireless sensor networks have been used widely in many application fields, whereas such applications as battlefield information obtaining, disaster survivor rescuing, etc. need an immediate and fast route that is simultaneously secure and energy-efficient. In this paper, by constructing a neighbor table, we build a tree-structure route that can meet all the above requirements for the large-sized wireless sensor networks with only a resource-constrained sink node. Our proposed routing scheme has salient features: light overhead, quick formation, and immediate effectiveness. We also adopt some effective energy-conserving measures, such as data aggregation, node sleep, sink move and parent reselection, etc., to prolong the lifetime of wireless sensor networks. We show through experiments that our routing scheme can ensure adequately the security and energy-efficiency of the route request message and the sensing data.
