Abstract: In view of problems appear in location privacy protection for sink node of wireless sensor networks, a location privacy preserving routing algorithm for sink node based on security area was proposed. This protocol protected location privacy of sink node through methods such as sending real package or fake package probabilistic from safe area to unsafe area and forming a circular sink area around the sink node. Performance evaluation was compared between this proposed dynamic routing algorithm and existing one. Network simulation results show that the routing algorithm has advantages such as low energy consumption, small network delay, and high data transmission rate, and it can also make a good balance between location privacy protection of sink node and network energy consumption.

Key words: location privacy protection, fake package, secure area, circular sink area
