ABSTRACT
An ad-hoc wireless network is highly different considering dynamic stochastic process of its underlying links, leads
to link breaks during data transaction. Hence, to provide free flow data transaction, many routing algorithms have
the property of link recovery and maintenance procedures to minimize the loss of data during transmission.
However these routing method do not guarantee reliable data transmission in some special application conditions
with wide requirements on Packet delivery ratio and link quality of the network. Routing is a critical issue in
MANET and hence the focus of this paper is the performance analysis of different routing protocols used in the
wireless network. We evaluate the ability of a mobile ad hoc wireless network to distribute flows across robust
routes by introducing the robust throughput measure as a performance metric. The utility gained by the delivery
of flow messages is based on the level of interruption experienced by the underlying transaction. We describe the
mathematical calculation of a network’s robust throughput measure, as well as its robust throughput capacity. We
introduce the robust flow admission and routing algorithm (RFAR) to provide for the timely and robust transport
of flow transactions across mobile ad hoc wireless systems.
