ABSTRACT
This chapter focuses on the design of multichannel communication based on the 802.11 distributed coordination function over a single radio for Wireless Sensor Networks (WSNs) in order to improve its communication performance, that is, throughput, end-to-end delay, and channel access delay. It focuses on multichannel assignment Medium Access Control protocol for contention-based Wireless Sensor Networks in order to efficiently utilize the medium by having node options to switch channels during congestion. The chapter considers a WSN that streams high data rates and not the traditional WSN that periodically sends data to its sink node. It explores multiple nonoverlapping channels with minimum overhead for increased capacity and minimum power usage. Multiple nonoverlapping channels present in the Institute of Electrical and Electronics Engineers 802.11 industrial, scientific, and medical free frequency band have been exploited by mapping them to multiple radios to increase overall capacity and connectivity of the wireless mesh network’s backbone.
