Multihop adhoc wireless networks offer great challenges for protocol designers. Stations in such networks are contrained 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 problems. The 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 dual MAC. This work discusses architecture and working of the dual MAC. Performance results of the network using MAC are presented, and compared with that of pure DCF operation. |
