Design and Evaluation of an IEEE 802.11 Based Dual MAC for MANETs
Abstract
Multihop ad-hoc wireless networks offer great challenges for protocol
designers. Stations in such networks are constrained by factors like low
power, limited bandwidth, link errors, and collisions. Changes are
needed at various levels of the protocol stack, most importantly at the
medium access layer (MAC). The medium access mechanism in multihop
wireless networks should minimize collisions, and take care of the
hidden and exposed node problems. The IEEE 802.11 MAC with Distributed
Coordination Function (DCF) does not scale well in such networks. We
introduce Point Coordination Function (PCF) in the region of high traffic
areas, and discuss its effect on network performance. To improve network
scalability and throughput, we propose the design of a new MAC called
Dual MAC. This work discusses architecture and working of the dual MAC
in detail. Performance results of the network using dual MAC are
presented, and compared with that of pure DCF operation.
