First, we discuss the channel heterogeneity by measuring the RSS values of a single link per second for each IEEE 802.11a channel in a round-robin fashion.…”

In HMesh, each node is equipped with multiple NICs and forms a tree architecture rooted at a sink node to deal with the traffic distribution of WMSNs.…”

In wireless multimedia sensor networks (WMSNs), disaster control and public safety are crucial issues that focus on emergency management, rescue, and emergency medical services. For high data rate requirement of WMSNs, the IEEE 802.11 specification can be used for the radio interface of sensor nodes, and the nodes can be equipped with multiple 802.11 radios to utilize multiple channels and link data rates. In practical IEEE 802.11 WMSNs, a link shows different link qualities depending on the operating channels and interfaces between two nodes, called channel and interface heterogeneity. In multirate WMSNs, low-rate links severely degrade the capacity of high-rate links, known as rate anomaly. In this article, we propose a novel channel assignment protocol, heterogeneity-aware mesh (HMesh), to address both rate anomaly mitigation and the channel and interface heterogeneity in real IEEE 802.11 WMSNs. HMesh constructs a tree-based WMSN using the proposed channel assignment and routing metric and the heuristic channel assignment algorithm. With the metric and heuristic algorithm, HMesh separates different data rate links by considering the channel and interface heterogeneity. Through extensive simulations and experiments on our IEEE 802.11 WMSN test bed, we demonstrate that HMesh significantly outperforms existing channel assignment protocols in IEEE 802.11 WMSNs.

SUMMARYProviding multichannel functionality can improve the performance of wireless networks. Although off‐the‐shelf IEEE 802.11 physical layer and medium access control specifications support multiple channels and multiple data rates, one of the major challenges is how to efficiently utilize available channels and data rates to improve network performance. In multirate networks, low‐rate links severely degrade the capacity of high‐rate links, which is known as performance anomaly. To overcome the performance anomaly problem, different data rate links can get equal air‐time by exploiting time diversity and frequency diversity, or they can be separated over nonoverlapping channels. In this paper, we study existing multichannel protocols proposed to mitigate the performance anomaly problem by classifying them into single‐radio protocols, multiradio single‐hop protocols, and multiradio multihop protocols. To investigate the effectiveness of multichannel solutions for performance anomaly, we compare these protocols with well‐known multichannel protocols that do not consider performance anomaly. In addition, this paper gives insightful research issues to design multichannel protocols that mitigate performance anomaly in IEEE 802.11 wireless networks. Copyright © 2012 John Wiley & Sons, Ltd.
