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
