Abstract:
With the rapid development of the Internet of Things, the location privacy is considered as an important security issue in sensor networks. Traditional encryption methods cannot effectively prevent attackers finding the position of monitoring object by reverse tracing. To solve these problems and considering attackers have enhanced visibility, we propose a location privacy protection strategy called PRABNS (phantom routing based on area and brother neighbor selecting). The strategy can make the phantom nodes evenly distributed around the source node, and the adjacent data packet have a certain angle space through the selection of partial region, and thus it can increase the diversity for the path of source node to the base station by selecting sibling nodes. The simulation results show that the strategy can provide better privacy preservation, and extend the secure time without increasing too much energy consumption.
