Channel sharing strategy through Media Access Control (MAC) protocols for avoiding collision is a challenging issue in Ad hoc networks. Deploying two distinct approaches, Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) and Wireless Token Ring Protocol (WTRP) play pivotal roles in MAC sublayer management. These protocols have been used in a variety of networks ranging from Internet of Things (IoT) to low rate tactical links in High Frequency (HF) band. In this paper, we investigate the operational algorithms of CSMA/CA and WTRP protocols and compare them via simulation in NS-3 simulator. The two protocols are evaluated and the appropriate protocol in terms of delay and throughput is chosen for networks with varying load, which is affected by node and packet number. Our results show that in networks with light load where high throughput is warrantied, CSMA/CA outperforms WTRP in terms of delay. However, algorithm of WTRP leads to higher throughput in networks with heavy traffic.
