Network Scheduling

This book studies wireless scheduling by jointly
optimizing the physical (PHY) layer and the medium-
access-control (MAC) layer. It consists of the
following three main thrusts.

In the first thrust, rate optimization for multicast
communications at the MAC layer is studied. For
Threshold-T based multicast policies, the
transmission rates are optimized to maximize the
network throughput. To ensure multicast reliability
when no retransmission is required at the MAC layer,
transport layer erasure coding is used for
reliability enhancement.

The second thrust focuses on distributed
opportunistic scheduling (DOS) for throughput
maximization in wireless ad hoc networks based on
random access. We characterize the optimal
scheduling policies based on different network
models.

The third thrust is on developing a cross-layer
optimization framework for effective
interference management towards understanding the
fundamental tradeoffs among possible
MIMO gains in multi-hop networks.
