Abstract:  Existing source location privacy preserving protocols applied to WSN use random walk, and the routing energy is hard to control. In order to solve this problem, this paper proposed a protocol based on controllable energy consumption (CEP). The proposed protocol took the distance of nodes as measure of energy consumption and created a 3-phase route between source node and sink node using controllable energy consumption. CEP increased the diversity of the routing path through phantom route phase, annular route phase, and credit route phase. Theoretical analysis and simulation experiment show that, the proposed strategy enhances safety of source node and controls the energy consumption.
