CDMA is most widely used standard for multiuser system in wireless adhoc network. CDMA standards present set of protocols for power control, BER control and multiuser detection system in adhoc networks. Therefore behaviour of MANET depends upon the modelling of CDMA based MAC layer, which also attributes to the performance of the network. We can summarize the section in short by claiming that in ADHOC network selecting the nodes is difficult due to hidden terminal and collision problems. Hence CDMA based technique is best to find out the suitable nodes in transmission. Further selecting those nodes which can be reached with minimum power loss is the best solution for such a problem. Hence we propose a CDMA based MAC protocol for MANET and select the closest geographical nodes with minimum power loss for routing. In this paper we present a means of improving the performance of the network by adopting a CDMA based scheduling algorithm.
