Method for identity, route and location anonymity in wireless sensor networks

摘要

An identity based on a current position within a wireless sensor network, a route and a location anonymous method are provided to protect the identity of the source node, the route, the location and the generated packet when transmitting the packet to a base station. Each sensor node preserves a magnetic track of a sink node(S21). The neighboring nodes of each sensor node is classified based on current location of the sink node according to direction(S22). The adjacent node of each sensor nodes is classified based on the link reliability according to the confidence(S23). The periodic update which a GPS(Global Positioning System) or the sink node transmits is used in the magnetic track.
