Security Threats for the Neighborhood Discovery Protocol (NHDP)
Abstract
This document analyzes common security threats of the Neighborhood
Discovery Protocol (NHDP) and describes their potential impacts on
Mobile Ad Hoc Network (MANET) routing protocols using NHDP. This
document is not intended to propose solutions to the threats
described.
