• Summary
• Conclusion

Introduction

• Mobile vs. Moving Sensor nets
• Challenges For Routing Protocol Design
• Scalability
• Energy Efficiency

4
Types of Routing Protocols

• Query/Data Driven
• Cluster based
• Location
• GAF
• GEAR
• PAGER-M

5
GAF (Geographic Adaptive Fidelity)

• Energy aware and Location based
• Virtual Grid
• States in GAF
• Discovery
• Active
• Sleep

6
GEAR (Geographic and Energy Aware Routing)

• Based on query driven Protocols
• Estimated cost and Learned cost
• Forwarding packets towards target region depends
  on estimated and learned cost
• Forwarding packets within region using recursive
  geographic forwarding

7
PAGER-M (Partial-partition Avoiding
GeographicRouting-Mobile)
The mobile sensor network model.
(a) At t0, node x has node z as a neighbor that
is moving out of its communication range. (b)
At t1, node z has moved out of the communication
range of node x, while node y has moved into the
communication range of node x and become a new
neighbor of x.

Conclusion

• Can we ever have a single Protocol?
• TCP/IP for WWW
• Can we have a standard/framework?
• Can it be easier?
