ad hoc / infrastructure and low/high mobility

Solutions:
infrastructure, low mobility -> Mobile IP
infrastructure, high mobility -> Cellular, Thin AP
ad hoc, low mobility -> Routing tables
ad hoc, high mobility -> ?

Lessons learned from
1. location management in Skype (Global Index, GI)
2. location management in OceanStore

Requirements of location management mechanism
1. no exhaustive search
2. bounded time to store location information at node(s)
3. bounded time to retrieve location information from node(s)

Reading Assignments:
Chap. 4 for general wireless Internet and
Section 4.3 for Mobile IP
