ABSTRACT
In this paper, we consider the security of geographical for-
warding (GF) a class of algorithms widely used in ad hoc
and sensor networks. In GF, neighbors exchange their loca-
tion information, and a node forwards packets to the desti-
nation by picking a neighbor that moves the packet closer
to the destination. There are a number of attacks that are
possible on geographic forwarding. One of the attacks is
predicated on misbehaving nodes falsifying their location in-
formation. The first contribution of the paper is to propose
a location verification algorithm that addresses this prob-
lem. The second contribution of the paper is to propose
approaches for route authentication and trust-based route
selection to defeat attacks on the network. We discuss the
proposed approaches in detail, outlining possible attacks and
