Cross-layer Based Congestion Control and Scheduling for MANET

The emerging MANET is extending the scope of resources to
mobile devices and sensors that are connected through
unreliable networks. Nowadays the number of mobile device
users is increasing dramatically and the mobile devices
provide various capabilities such as location awareness that
are not normally incorporated into fixed mobile resources.
Nevertheless, the mobile devices exhibit inferior
characteristics such as poor performance, limited battery life,
and unreliable communication, compared to fixed Grid
resources. While routing the network, packet loss occurs due
to link failure and congestion. Focusing on packet drop due to
link failure results in the loss of resources, hence packet loss
due to congestion is given a vital importance. This paper
proposes to develop a jointing scheduling and congestion
control in a multi hop MANET First, this paper present a
cross layered model of energy efficient congestion detection
and control mechanism. By identifying the causes of MAC
layer packet drops, unnecessary route error propagations and
route re-discovery procedures can be avoided. Once a wireless link experiences packet loss at MAC layer due to signal interference, it can be inferred that the contention area in which the link resides is congested.
