Mobility
Metrics:
|
|
|
|
n |
parameters
that represent current mobility status a node can monitor
|
|
|
|
n |
Proposed:
no. of link breaks,
relative mobility, link duration etc.
|
|
|
|
n |
Selection
rule: simple, certain accuracy, not require extra equipment,
|
|
impact
on routing protocol performance (here, PDR)

Simulation
Environment:
|
|
|
|
n |
NS2,
80 (170 for MH ) nodes in 1000x1000 m area, time: 900s
|
|
|
|
n |
Mobility
models: RWP, MH and RPGM
|
|
|
|
l |
Aside:
RWP, RPGM match well empirically observed human mobility
|

|
n |
Traffic:
CBR, 25 sources, 4 packets/s with 64 bytes size/packet
|
|
|
|
n |
Routing
protocols: AODV, DSR and OLSR
