A Routing Protocol for Source Location Privacy in Wireless Sensor Networks with Multiple Sources

In Wireless Sensor Network (WSN) applications, such as monitoring valuable assets, the locations of assets should be kept private to hide the assets from adversaries. Much of the work that solves this problem, called Source Location Privacy (SLP) problem, has focused on networks where only a single source reports to the sink at a time. Therefore, existing solutions for the SLP problem may not show the same performance in networks where multiple sources report simultaneously. In this paper, we present a routing algorithm called Red paths to solve the SLP problem for WSNs with multiple sources. We perform simulation experiments and show that Red paths offer better location privacy, with a low message overhead, not only in networks with a single source but also in networks with multiple sources.
