Abstract

Abstract — Wireless technologies, such as IEEE 802.11a, that are used for ad hoc networks provide for multiple nonoverlapping channels. Most ad hoc routing protocols that are currently available are designed to use a single channel. The available network capacity can be increased by using multiple channels, but this requires the development of new protocols specifically designed for multi-channel operation. This paper presents protocols for improving the capacity of multi-channel wireless networks. Our protocols simplify the use of multiple channels by using multiple interfaces, although the number of interfaces per node is typically smaller than the number of channels. We propose a link layer protocol to manage multiple channels, and it can be implemented over existing IEEE 802.11 hardware. We also propose a routing protocol that operates over the link layer protocol, and is specifically designed for multichannel, multi-interface ad hoc wireless networks. Simulation results demonstrate the effectiveness of the proposed approach in significantly increasing network capacity, by utilizing all the available channels, even when the number of interfaces is smaller than the number of channels. Index Terms — Ad hoc networks, routing, multiple channel, multiple interfaces I.
