Mobile Ad-Hoc Communication

Abstract — we find out various power aware and data packet rate control with-collision-avoidance (CSMA/CA)-based ad hoc wireless network communication. And identifies that CSMA/CA based technique are more flexible for wireless mobile ad-hoc communication that gives congestion information to all senders ’ nodes and if anywhere congestion found in the network then minimize the data packet rate control the congestion from the network. In his approach also find out the number of collision packets at the time of communication. With the help of MAC and 802.11 standards resolve the problem of collision and congestion in MANETs. And main focus of enhance the network performance like throughput, packet delivery ratio, transmission power consumption and congestion minimization using MAC layer based CSMA/CA approach. The above approach is simulated through network simulator (NS-2). Index Terms—Ad hoc network, IEEE 802.11, power/rate control, MAC
