Abstract

It is generally admitted that the performance of ad hoc networks can be quite poor and disappointing due to high contention and lack of an optimal MAC protocol. Here we investigate one approach to alleviate the contention: allowing nodes to communicate simultaneously on different channels by configuring them with multiple radios. Though simply adding radios improves throughput, a more dramatic enhancement can be obtained when using an interferenceaware routing metric, which improves the TCP throughput by an average of 89% against single radio network.
