Research on end-to-end location privacy protection in case of multi-source node in WSNs
propose a privacy protection scheme based on bidirectional tree topology( BTBLPS). The scheme adopts the shortest path method to transmit real data packets
and then on intersection of the shortest path produce fake packet transmission branch of bidirectional. Among them
fake packet transmission direction of branch near source node is from branch node at the end to intersection
and the side near base station
is contrary
in order to realize location privacy protection of source node and base station at the same time. Theoretical analysis and simulation results show that the proposed scheme is feasible
