Designing a Medium Access Control (MAC) protocol for wireless ad-hoc networks by using in-band full-duplex wireless communications for disaster management

This is the era of wireless communication. The demands of wireless ad-hoc networks are increasing day by day with the advancement of new technologies and standards for wireless communications. Among the different issues, in-band full-duplex (IBFD) communication technique has been contributing significantly for the development of the standard of current wireless communication setup. To handle a huge volume of traffic, IBFD is superior than traditional FD communication. Although a significant number of medium access control (MAC) protocols are proposed for wireless local area networks (WLANs) using IBFD techniques, this number is very few for ad-hoc networks. This research proposes a MAC protocol for ad-hoc networks using IBFD wireless communications, which is named as AdHoc-FDMAC. Here, an ad-hoc network model is proposed for which the MAC protocol is designed where all the nodes are full duplex capable. The proposed protocol modifies a number of control frames in IEEE 802.11 distributed coordination function (DCF) MAC standard. Here, the detailed time sequences for all types of FD communications are shown for the data transmission and routing. Additionally, the probability equations are derived for all types of FD communications as well as throughput equations are derived for all types of FD and HD communications. The performance analysis is executed in terms of probability analysis, throughput analysis and routing time.  According to the throughput analysis, the maximum throughput for the proposed AdHoc-FDMAC is 48.34 Mbps, which is much better than that of traditional MAC protocols for ad-hoc networks. This AdHoc-FDMAC outperforms the existing ad-hoc MAC protocol by 16.80% throughput gain. Moreover, this MAC protocol has reduced the time latency for routing as compared to the traditional ad-hoc on-demand distance vector (AODV) routing. This research compares the routing time of IBFD based AODV with the conventional AODB. The result shows that IBFD based AODV requires 33.33% less routing time than that of the conventional AODV.
