A new efficient and robust MAC protocol against multipath fading for ad hoc networks

Abstract

Wireless ad hoc networks attract interests of researchers. In such networks, data packets are relayed by nodes from a source node to a destination node. This is referred to as multi-hop communication. For such system, it is known that the IEEE802.11 DCF is not efficient. Then, in order to improve the efficiency, several methods were proposed conventionally. However, most of them are not aware of realistic radio environments considering multipath fading. Therefore, the conventional methods can be damaged seriously under multipath fading. In this paper, we propose a new MAC protocol for wireless ad hoc networks, that is robust against multipath fading.
