Abstract-- We present the Pulse protocol which is designed
for multi-hop wireless infrastructure access. While similar to the
more traditional access point model, it is extended to operate
across multiple hops. This is particularly useful for conference,
airport, or large corporate deployments. In these types of environ-
ments where users are highly mobile, energy efficiency becomes
of great importance. The Pulse protocol utilizes a periodic flood
initiated at the network gateways which provides both routing
and synchronization to the network. This synchronization is used
to allow idle nodes to power off their radios for a large percentage
of the time when they are not needed for packet forwarding.
This results in substantial energy savings. Through simulation
we validate the performance of the routing protocol with respect
