Rate matching: a new approach to hidden terminal problem in ad hoc networks

Prior works on the hidden terminal problem in wireless networks often assume that the SNR requirement and the transmission range in a network are fixed. In fact, they are rate dependent. Because of this assumption, many of the prior conclusions about the hidden terminal problem are not accurate. A n...

Description
Summary:Prior works on the hidden terminal problem in wireless networks often assume that the SNR requirement and the transmission range in a network are fixed. In fact, they are rate dependent. Because of this assumption, many of the prior conclusions about the hidden terminal problem are not accurate. A new analysis of the hidden terminal problem is presented in the paper. The new insights provided by the analysis lead to a rate-matching scheme for tackling the hidden terminal problem in wireless networks. The new method is simple, yet efficient, and requires no protocol changes from the 802.11 standard. NS2-based simulations are given in the paper to demonstrate the advantages of the new scheme.
