Fog Computing
optimization
challenges
Network
Federation
deploy controllers
Fog Nodes
deal with latency, scalability,
mobility.
HetNets
efficient instantiation, placement, migration
Software Defined Networks (SDN)
dynamic conditions,
unreliable links.
Network Function Virtualization (NFV)
virtualize gateways, switches, load balance,
firewalls, intrusion detection.
QoS
Connectivity
reduce cost, trimming data, expand.
partitioning the sensor network
strategies to select online AP
Reliability
clustering, grid, cloud, and sensor requirements
Handover + process migration
Capacity
network bandwidth, storage, cache
how and where place the data?
Interplay Fog and Cloud
Delay
real-time stream processing, CEP
Foresee query region for moving consumers
Start the event processing early
Unified interface &
Programming Models
App-centric computing
orchestrate dynamic,
hierarchical, and heterogeneous
resources
different platforms
Computation
Offloading
dynamic principles to span the computation
Granularity decisions
dynamic partitioning
different hierarchy on Fog and Cloud
Account, Billing,
and Monitoring
price or fraction of the payment
specific granularity for the environment
maximize the revenue and utilization of Fog
industrialize airline ticketing,
car rental, hotels.
Security &
Privacy
Authentication &
Authorization
Different level of Fog
Fine-grained data access
control on Cloud & Fog
Policy to resource access control
strategies for intrusion detection
and privacy leakage
Provision &
resource management
metrics for bandwidth, storage,
computation, and latency
leverage the end nodes
strategies to do resource
discovering and sharing
save energy in HetNet
