Executive Summary

Positioning of nodes in a Wireless Sensor Network (WSN) is a process that allows location-unaware nodes to discover their spatial coordinates. This process requires the cooperation of all the nodes in the system. Ensuring the correctness of the process, especially in the presence of misbehaving nodes, is crucial for ensuring the integrity of the system. The authors analyze the problem of unaware nodes determining their location in the presence of misbehaving neighboring nodes that provide false data during the execution of the positioning process. They divide and present potential misbehaving nodes in four different adversary models, based on their capacities.
