Abstract
Mobile Ad hoc NETworks (MANETs) are networks in which mobile routers are connected via wireless links forming dynamic topologies.They are self organizing and autonomous networks, consisting of mobile nodes that act as routers and collaborate with one another to form a network. A Monitor for Mobile ad Hoc networks (MMAN)can be a solution for dynamic assessment of individual node
cooperation in forwarding packets for their neighbors, which helps identify selfish and malicious nodes in a MANET.
Selfishness
Selfishnessis a behaviour where a node or a group of nodes in a
MANET refuses to forward their peers packets, could
significantly affect the performance of a MANET.
Solution
Behavior-based solutions have been proposed to
detect selfish or malicious behavior in the network which is an approach that tend to be suited to the self-organized nature
of a MANET as nodes evaluate the behavior of their
peers, share their evaluations, and dynamically adjust
their own behavior. When a particular node is a non-cooperative one,
all other members of the network avoid requesting or
providing services from and to the misbehaving or selfish
node.
Requirements:
This system require either
secure hardware or a tamper-proof software suite to be
installed on all network nodes.Besides, to monitor and
report misbehavior, nodes have to consume their
CPU power,battery, and bandwidth.
MMAN relies on multiple monitoring stations that
collaborate and combine information to maintain an
accurate and up-to-date view.Many Monitoring Units (MUs) are deployed
throughout the MANET which are responsible for
collecting information regarding network behavior.The
information collected by the MUs is delivered to
management nodes, where they are analyzed and presented on a GUI. With MMAN, detecting selfishness is very robust
under high-volume traffic.
