A Cooperative Multi-Channel MAC Protocol for Wireless Networks
 

Summary: A Cooperative Multi-Channel MAC Protocol for
Wireless Networks
Devu Manikantan Shila, Tricha Anjali and Yu Cheng
Abstract--One of the crucial challenges in practical wireless
networks is how to provide robust communication over fading
channels. Recently, cooperative communications have emerged as
a promising approach to achieve spatial diversity and thereby
reduce the negative effects of fading on wireless channels. Never-
theless, a few existing works indicate that deploying cooperative
relays in large-scale wireless networks can lead to an elevated
level of interference which in turn leads to degraded throughput
and higher packet losses. It is also well-known that the use of
multiple frequency channels can mitigate the wireless interference
to a greater extent and thus improve the overall performance of
a wireless network. Therefore, it is interesting and important
to design and evaluate protocols that can provide the combined
potential of both cooperation communication and multiple chan-
nels. In this paper, we propose a novel cooperative multi-channel
MAC protocol that integrates the capabilities of both multiple
channels and cooperative communications at the MAC layer to
