Routing Schemes for Source Location Privacy in Wireless Sensor Networks : A Survey
Lilian Charles Mutalemwa, Seokjoo Shin · 한국통신학회논문지 · 2018
Wireless Sensor Networks (WSNs) are used in sensitive applications such as monitoring of high value assets. One of the challenges facing these networks is preservation of source location privacy. In this work, a review of performance characteristics of some representative routing schemes is done. Performance analysis of the schemes shows that tree-based routing schemes can provide high privacy at a cost of high energy consumption while angle-based routing schemes provide a good balance between privacy and energy consumption. The work also highlights some challenges and open issues for the routing schemes.
