Adaptive: What do I mean?
,“Environment”
means many things
–Radio environment:
could impact route stability and throughput
–Traffic pattern:
which flows, between which nodes
–Mobility: topology
changes, formation/destruction of links
,First
step: adapt to mobility at short time-scales
–Identify mobility metric that
,Captures
the mobility-driven impact of routing protocol performance
,Can
easily be measured by a node, no extra hardware required
,Is true
across a number of mobility scenarios (different patterns/mobility models) and independent of mobility model parameters
(RWP: Max/min speed,
pause time, …)
–Based on the metric, modify protocol to allow
individual nodes to adapt their protocol
behavior
