Multichannel, multihop wireless networks can improve system performance by allowing more simultaneous transmissions in the network than when compared to a single channel network. This in turn results in a higher network throughput and improved spectral efficiency. In order to maintain connectivity across nodes that operate on different channels, most of the existing multichannel implementations propose to switch the channels on the wireless radios. However, due to both software and hardware restrictions switching channels incur a significant delay, which can be prohibitive for many delay sensitive, real time applications, such as VoIP and interactive gaming.
