IntroductionMobile vs. Moving Sensor nets

Challenges For Routing Protocol Design

ScalabilityEnergy Efficiency

Types of Routing ProtocolsQuery/Data Driven

Cluster based

LocationGAFGEARPAGER-M

GAF (Geographic Adaptive Fidelity)

Energy aware and Location basedVirtual GridStates in GAF:

DiscoveryActiveSleep

GEAR (Geographic and Energy Aware Routing)Based on query driven ProtocolsEstimated cost and Learned costForwarding packets towards target region depends on estimated and learned costForwarding packets within region using recursive geographic forwarding

PAGER-M (Partial-partition Avoiding GeographicRouting-Mobile)

The mobile sensor network model.

(a) At t0, node x has node z as a neighborthat 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 ofnode x and become a new neighbor of x.

(a) (b)

A Novel Scheme based on polar bonds

ConclusionCan we ever have a single Protocol?

TCP/IP for WWWCan we have a standard/framework?Can it be easier?
