Abstract-More and more wireless networks are deployed with overlapping coverage. Especially in the unlicensed bands, we see an increasing density of heterogeneous solutions, with very diverse technologies and application requirements. As a consequence, interference from heterogeneous sources-also called cross-technology interference-is a major problem causing an increase of packet error rate (PER) and decrease of quality of service (QoS), possibly leading to application failure. This issue is apparent, for example, when an IEEE 802.15.4 wireless sensor network coexists with an IEEE 802.11 wireless LAN, which is the focus of this work. One way to alleviate cross-technology interference is to avoid it in the frequency domain by selecting different channels. Different multichannel protocols suitable for frequency-domain interference avoidance have already been proposed in the literature. However, most of these protocols have only been investigated from the perspective of intratechnology interference. Within this work, we create an objective comparison of different candidate channel selection mechanisms based on a new multichannel protocol taxonomy using measurements in a real-life testbed. We assess different metrics for the most suitable mechanism using the same set of measurements as in the comparison study. Finally, we verify the operation of the best channel selection metric in a proof-of-concept implementation running on the testbed.Index Terms-IEEE 802.11, IEEE 802.15.4, interference avoidance, MAC, medium access control, RDT, receiver directed transmission, WiFi, wireless sensor networks, ZigBee. I. CROSS-TECHNOLOGY INTERFERENCE AVOIDANCE: WHYAND HOW? IT IS increasingly hard to imagine a world without wireless communication. Today, we experience an exciting time given the emergence of the Internet of Things, which will allow any identifiable object in the world to communicate. Most objects will connect wirelessly, for obvious reasons. Hence, we can safely assume that the number of wireless devices will continue to grow exponentially [1]. Not only does the quantity of devices grow, but also the application domains diversify. Different application domains impose different requirements on the network, e.g., the quality of service (QoS) it needs to deliver, or the limitation on power consumption of network nodes that operate on batteries. These diversifying requirements can no longer be supported by a single wireless technology. Even more, within a single environment, multiple wireless technologies are being deployed in order to fulfill the applications needs. Hence, coexistence of different technologies is becoming increasingly important.The coexistence of different technologies is particularly challenging when they share the same frequency band. Representative of such a situation are the unlicensed frequency bands, which are used by an increasing number of wireless technologies. As a result, different technologies that have not been designed to coexist need to operate in the same frequency bands, leading to re...

“…However, those protocols typically select shortest-path routes, which may not be suitable for multi-channel networks [3]. Shacham et al [15] have proposed an architecture for multichannel wireless networks that uses a single interface. However, the proposed architecture may affect network connectivity and requires complex coordination.…”

“…A multi-channel multi-hop network architecture has been considered in [15] in which each node has a single transceiver, and nodes have a quiescent channel to which they tune when not transmitting. A node wishing to communicate with a destination tunes to its quiescent channel, and transmits the packet to a neighbor whose quiescent channel is the same as that of the destination.…”

This paper argues for the need to address the issue of multi-channel network performance under constraints on channel switching. We present examples from emergent directions in wireless networking to motivate the need for such a study, and introduce some models to capture channel switching constraints. For some of these models, we study connectivity and capacity of a wireless network comprising n randomly deployed nodes, equipped with a single interface each, when there are c = O(logn) channels of equal bandwidth W c available. We consider an adjacent (c, f ) channel assignment where a node may switch between f adjacent channels, but the adjacent channel block is randomly assigned. We show that the per-flow capacity for this channel assignment model is Θ(W f cn logn ). We then show how the adjacent (c, 2) assignment maps to the case of untuned radios. We also consider a random (c, f ) assignment where each node may switch between a pre-assigned random subset of f channels. For this model, we prove that per-flow capacity is O(W
