Abstract
A mobile Ad-hoc network (MANET) is consists of mobile platforms which are simply referred
to as "nodes" which are free to move about arbitrarily without requiring centralized
administration or fixed network infrastructure. The nodes may be in or on airplanes, ships,
trucks, cars, perhaps even on people or very small devices, and there may be multiple hosts per
router. Through cooperatively forwarding packets for each other, nodes in mobile Ad-hoc
networks can communicate with other nodes out of their direct transmission ranges. MANET
nodes are equipped with wireless transmitters and receivers using antennas which may be
omnidirectional (broadcast), highly-directional (point-to-point), possibly steerable, or some
combination thereof. In many situations, such as military or emergency applications, nodes in
an Ad-hoc network belong to the same authority and pursue the common goals. Under such
circumstances, fully cooperative behavior, such as unconditionally forwarding packets for each
other, can be assumed. We refer to such Ad-hoc networks as cooperative Ad-hoc networks.
The common theme of most research in this area is to optimize physical layer performance
measures without considering in much detail how cooperation interacts with higher layers and
improves network performance measures. Because these issues are important for enabling
cooperative communications to practice in real-world networks, especially for the increasingly
important class of mobile Ad-hoc networks.
Cooperative routing technology can efficiently improve the performance of the network by
initiatively selecting cooperative nodes to forward the data. In this research, cooperative
routing algorithms is proposed and implemented in mobile Ad-hoc networks and the
performance of the proposed cooperative Ad-hoc algorithms are compared with noncooperative
