Design and Evaluation of MAC Protocol Strategies Techniques in Wireless Ad Hoc Network

Wireless communication has become a core part of modern communication technology. The Infrastructure less wireless network, commonly referred to as Ad Hoc networks, has attracted extensive research interest for past 30 years. In this work, the focus is on IEEE 802.11 network performance analysis of Multihop hop Ad Hoc networks under non-saturated network conditions. To meet the increasing demand of multimedia, it is necessary to provide the quality of service in such networks. The current work presents the development of an analytical model for network performance analysis. The medium access mechanism in multihop wireless networks should minimize collisions, and take care of the hidden and exposed node problems. The IEEE 802.11 MAC with Distributed Coordination Function DCF does not scale well in such networks. We introduce Point Coordination Function PCF in the region of high traffic areas, and discuss its effect on network performance. To improve network scalability and throughput, we propose the design of a new MAC called Dual MAC. This work discusses architecture and working of the dual MAC in detail. Performance results of the network using dual MAC are presented, and compared with that of pure DCF operation.
