An Ad-hoc network is a dynamic network farmed on demand by a group of nodes without any pre-existing network infrastructure. Self configurability and easy deployment feature of the Mobile Ad-hoc NETwork (MANET) resulted in numerous applications in modern era. An efficient and effective Medium Access Control (MAC) protocol is essential in ad-hoc network for proper sharing of channel. The omnidirectional antenna has been used in traditional MAC protocols. More intensive attention is given toward the directional antenna by researchers due to capability of spatial reuse and other beneficial features.
