Search
Methods in
Dynamic
Wireless Networks
No full
support for routing and search can be given in
qWireless
and mobile networks
qSensor
networks
qOverlay,
peer-to-peer networks
Advantage: More flexibility to set up and
expand networks,
less overhead in
managing networks with high churn
Disadvantage:
More expensive search by exploration of the network
The
Internet itself exhibits unstructured growth and churn, but
qthe IETF
(Cisco, Juniper ...) established reliable routing and
qsearch
engines (Google, Yahoo, …) provide
content exploration
qNew IETF
WG on “Routing
for low power & lossy Networks”
Challenges
for search in wireless networks
