A Survey on Achieving Source Location Privacy and Network Lifetime Maximization in Wireless Sensor Networks

Abstract

 In recent years, Wireless Sensor Network has drawn considerable attention from research community due to
wide range of applications used. The most notable challenge which is threatening the WSN is source location privacy.
Preserving the source location means hiding the physical location of the source from the adversaries and increasing
difficulty for adversaries in tracing the message path back to the source location. Although many of the privacy related
schemes such as Phantom routing has been established, still there exists problem with source location privacy. This
paper focuses on one solution namely Tree-based Diversionary Routing scheme. The main goal of Tree based
diversionary routing is to improve performance in two aspects: privacy and network lifetime. The idea behind Tree-based
Diversionary Routing scheme is to create diversionary routes along the path from source to sink and at the end of each
route, Fake node is present. This increases difficulty for adversaries in tracing the path and identifying the source node.
At the same time, Network Lifetime is also maximized by minimizing the energy consumption in hotspot region and
utilizing that energy in creating the diversionary routes in non-hotspot region. The Directed oriented attack which leads
the adversaries to identify source node easily can also be avoided
