A MAC Protocol for Multi-Packet Ad-hoc Wireless Network Utilizing Multi-Antenna

In this paper, we propose a novel multi-antenna utilization scheme for avoiding the packet congestion around the gateway (GW) of the ad-hoc wireless networks. In our previous work, we have discussed the number of antenna design for suitable for packet congestion around the GW. However, only multi-user access with multi-antenna is considered at the receiver node. Moreover, we do not consider the effective media access control (MAC) protocol for this kind of networks. In this paper, in order to realize the effective multi-packet access ad-hoc wireless networks, we consider applying multi-input multi-output (MIMO) technique for packet transmission to the next hop node, and we also propose a MAC protocol avoiding the hidden node problem for supporting the multi-packet access with multi-antenna at the nodes around the GW.
