Mobility Metrics
wMobility Metrics:
nparameters that represent current mobility status a node
can monitor
nProposed: no. of link breaks, relative mobility, link duration etc.
nSelection rule: simple, certain accuracy, not
require extra equipment, impact on routing protocol performance (here, PDR)
wSimulation
Environment:
nNS2, 80 (170 for MH ) nodes in 1000x1000 m area, time:
900s
nMobility models: RWP, MH and RPGM
lAside: RWP, RPGM match well empirically observed human
mobility
nTraffic: CBR, 25 sources, 4 packets/s with 64 bytes
size/packet
nRouting protocols: AODV, DSR and OLSR
