摘要：In wireless ad hoc networks (WANets), multihop routing may result in a node knowing the content of transmissions of nearby nodes. This knowledge can be used to improve spatial reuse in the network, thereby enhancing network throughput. This paper is to develop overlapped transmission techniques based on this idea and analyze several factors affecting their performance. Then develop a MAC protocol based on the IEEE 802.11 standard to support overlapped transmission in a WANet. The resulting overlapped carrier-sense multiple access (OCSMA) protocol improves spatial reuse and end-to-end throughput in a random network scenario.
