Mobile ad hoc networks are infrastructure-less wireless networks; all nodes can quickly share information without using any fixed infrastructure like base station or access point. Wireless ad hoc networks are characterized by frequent topology changes, unreliable wireless channel, network congestion, and resource contention. Multimedia applications usually are bandwidth hungry with stringent delay, jitter, and loss requirements. Designing ad hoc networks which support multimedia applications, hence, is considered a hard task. The hidden and exposed terminal problems are the main which consequently reduces the network capacity. Hidden and exposed nodes reduce the performance of the wireless ad hoc networks. Access delay is the major parameter that is to be taken under consideration. Due to hidden and exposed terminal problems, the network suffers from a serious unfairness problem.

In this paper, we focus on IEEE 802.11e enhanced distributed channel access (EDCA) protocol, which can provide QoS guarantee for multimedia applications in mobile ad hoc networks. First, we briefly explain the concept of EDCA protocol. Then we implement EDCA protocol in GloMoSim via configuring special contention parameters for multimedia applications and introducing a virtual collision disposal mechanism in the MAC layer. In the end, we provide performance analysis for EDCA protocol through plentiful simulations. The simulation results show an excellent performance of the EDCA protocol we proposed.
