CROSS-LAYER DESIGN AND COOPERATIVE COMMUNICATIONS IN WIRELESS NETWORKS

This book is intended to present an overview and
specific applications of cross-layer
optimization and cooperative communications in
wireless networks. It
consists of three main thrusts. In the first thrust,
a cross-layer design approach is taken to
study rate control in multi-hop wireless networks.
Each flow is treated as a leaky-pipe flow and the
rate control is explored through effective network
utility maximization (ENUM). The second thrust
focuses on efficient data transport in wireless
sensor networks, where neighboring sensor nodes are
organized into coalitions and cooperative
communications can be carried out. Energy efficiency,
balancing, and probabilistic coverage and
connectivity are investigated in this study. The
third thrust is on the comparison between MIMO and
SISO configurations, where optimal stopping theory is
employed to investigate the optimal neighbor
selections in multi-channel networks for both antenna
configurations.
