The performances of the MA protocols are analyzed in wireless ad-hoc networks. The main objective is correct reception of packets at its intended receiver in wireless adhoc network and the analysis is made in terms of throughput, delay and outage probability. In particular, two MAC protocols, ALOHA and Carrier Sense Multiple Access (CSMA), are compared. A transmission of packet is considered successful, if the received SINR value is above a predefined threshold value within the specified packet duration. Appropriate limits on the delay and outage probabilities are obtained as a function of retransmissions, distance between transmitter and receiver, number of backoffs and the transmitter density, and in the case of CSMA, sensing threshold value also included.
