Admission Control Scheme and Bandwidth Management Protocol for 802.11 Ad hoc Networks

In this paper, we propose a new admission control scheme for 802.11 ad hoc networks. The scheme utilizes two criteria for accepting flows: one during the route request phase and the other during the route reply phase. The scheme achieves optimal results in terms of overhead and delay. However, it is based on high power transmissions that consume more energy power. We also propose a bandwidth management protocol that uses only two bits to refresh and release the bandwidth resources. The analytical study demonstrates that our scheme shows better performance compared to existing schemes.
