Secure routing based on the neighbor table in wireless sensor networks

In this paper, we build a secure and energy-efficient tree-structure route 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. By constructing a neighbor table that contains the related key and energy information, the security and energy-efficiency of the route request message and the sensing data can be ensured adequately. 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.
