Description

The term ad hoc networking typically refers to a system of network elements that combine to form a network requiring little or no planning. Ad hoc networks are cost-effective and easy to deploy. The channel access control mechanisms provided by the MAC layer are also known as a multiple access protocol. This makes it possible for several stations connected to the same physical medium to share it. In this project, the system proposes distributed multi-channel medium access control (MAC) protocol for Ad hoc wireless network. To evaluate the network performance in terms of the aggregate throughput. And to improve the network performance. Our proposed protocol enables hosts to utilize multiple channels by switching channels dynamically, thus increasing network throughput. The protocol requires only one transceiver per host, but solves the multi-channel hidden terminal problem using temporal synchronization. Our scheme improves network throughput significantly, especially when the network is highly congested. The simulation results show that our protocol successfully exploits multiple channels to achieve higher throughput than IEEE 802.11. Also, the performance of our protocol is comparable to another multi-channel MAC protocol that requires multiple transceivers per host. Since our protocol requires only one transceiver per host, it can be implemented with a hardware complexity comparable to IEEE 802.11. Media access control is an essential part of the wireless communication stack and it has obtained intensive research attention. More recently, to achieve higher communication throughput, multi-channel MAC has been studied.
