We question about multihop gets better performance than single hop in wireless networks. In this paper we design a new and simple multihop transmission model called PESR, performance enhancement of IEEE 802.11 by spatial reuse. We elect an intermediate node which between a source-destination pair for forwarding packets to become multihop instead of directly transmission from the source to the destination. By this way, we will have more links at the one time, the channel utilization should be grown and we will get better system performance. However, there is much overhead we have not considered. We will discuss the detail about overhead in coming sections. In fact, the results of simulation show that the performance is not present very well. And we wonder if the multihop in wireless networks is a pretty good idea.
