Abstract
The resource limitation of nodes used in selforganized
ad hoc networks, along with the multi-hop nature
of these networks, may cause a new behavioral phenomena
which does not exist in traditional infrastructured environments.
To save its energy, a node may behave sel shly, then
it would not forward packets for other nodes while using
their resources to forward its own packets. This deviation
from the normal behavior is a potential threat against
the service availability, one of the most important security
requirements. Resolving this problem is challenging, due to
the self-organization and the infrastructureless features of
these networks.
Recently, some solutions have been proposed, but almost all
these solutions rely on the watchdog technique [1], which
suffers from many problems. Especially when using the
power control technique, employed by some new poweraware
routing protocols following the watchdog's proposal.
To overcome this problem, we propose in this paper a new
approach we call two hops ACK (acknowledgment). Using
petri nets we model and analyze our solution based on this
novel approach.
