Abstract
The use of small portables and mobile devices has
made MANETs (Mobile Ad Hoc Networks) very popular. A
MANET is a network composed by a group of mobile nodes
without any fixed device or a central coordination. They work
in an open net and their collaboration is the sole means to
allow communications and the survival of the MANET itself.
A critical issue is to assess the behaviour of the nodes that
participate in the network, possibly identifying selfish conduct
that can compromise the functioning of the system. This paper
shows a method to evaluate the behaviour of all nodes by
establishing a reputation value that represents the trustworthiness
of each node.
A protocol is presented to calculate the reputation of a node
by locally observing the node from another one, and then tuning
this intermediate value with additional observations from
other participants. When the reputation value of a node is
available, it is stored into a node’s table. Moreover, all values
are shared and distributed uniformly over the network. So, all
participants are able to recognize all nodes that are part of the
net, between old and new ones.
This reputation protocol is viable. Each node can efficiently
calculate the reputation values of its neighbours and then of all
network nodes. In addition, it has been analysed through different
situations wherein nodes have taken several behaviours.
A variety of simulations conducted using the network simulator
NS-2 strongly support these claims.
