Wireless sensor networks (WSNs) are an important topic these days. Their use is related to a wide variety of applications, from sensor nodes placed at strategic locations to detect environmental information, to composing a mobile wireless mesh network. The latter situation happens when unmanned aerial vehicles (UAVs) are provided with a wireless mesh node, for example.

This paper presents an important study that focuses on the injection of false data that can be transferred from one node to another, improving the overhead in the network but providing incorrect results. This paper treats the problem.

The test and results that this paper explores maintain the integrity of the data, even when the authors use data aggregation, since more than one sensor can receive data and aggregate it.

The authors provide some background, and present assumptions and limitations to help readers understand the vulnerabilities and problems associated with this kind of technology. They address the most frequent attacks and problems, and propose a new protocol for providing greater security and detecting false data. They include all of the details of this protocol, as well as the algorithm for implementing the false data detection. Based on the performance evaluation, this protocol appears to be a good option, and is probably the first one to avoid false aggregation data with integrity.

The target audience for this paper consists of readers who understand the limitations, vulnerabilities, and uses of WSNs. This well-written paper is complete in its references, as well as in its presentation of the protocol, the algorithm, the security analyses, and all of the performance evaluations.
