Motivation
, QoS routing in MANETs
Supports interesting applications
Requires “accurate” state information
, Little work to quantify accuracy of state information
QoS routing protocols exist
State information aggregation discussed for LARGE wired networks, including loss
of information (ATM, hierarchical networks, etc.)
Some work on quantifying amount and accuracy of topology information
Existing evidence seems to suggest that
, More accurate state information results in “better” routing decisions
, More accurate state information is difficult to collect
, We are interested in energy-efficient routing, a key piece of state
information is the residual energy level of nodes
