Network S & V

• Softwarization of open networking

• Virtualization of network

Exploring Network S & V

by Applying SDN/NFV to 5G and IoT (cont.)

Major Trends of 5G and IoT

• Open Networking = SDN + NFV + Cloud Open Source

  • ​Key Elements: P4 and CORD

    • Programming Protocol-Independent Packet Processors

    • Central Office Re-architected as a Datacenter

• SDN/NFV 5G Services

• Disaggregation

Exploring Network S & V

by Applying SDN/NFV to 5G and IoT (cont.)

Three approaches for S & V for 5G

• Radio Access Network (RAN) approach

  • Virtualized RAN

• Core Network (CN) approach

  • Virtualized EPC (Envolved Packet Core)

• System-level approach

Mobile is Everything

5G is more than a faster 4G,
and application is the main driving force of 5G.

• Mobile broadband

• Massive Machine Type Communication (MTC)

• Ultra-reliable & low latency communication

Multi-cell Clustering in Green Heterogeneous Wireless Networks

Keynote Speech

Multi-cell Clustering in Green Heterogeneous Wireless Networks

科技部工程科技發展司司長

廖婉君教授

Power Consumption Breakdown

• BSs and their power amplifier are the most dominant ones.

  • ​About 1/3 from a single factor

• ​Two Basic Energy-Saving Approaches

  • ​BS Sleeping Control

  • Traffic Offloading (to small cells)

• ​Is Network Energy Efficiency Important?

Multi-cell Clustering in Green Heterogeneous Wireless Networks (cont.)

Green Multi-cell Clustering in HetNets

• Heterogeneous Network (HetNets)

• Green Multi-cell Clustering =
  BS Sleeping Control + CoMP Clustering

  • ​Coordinated Multipoint (CoMP) Clustering

Multi-cell Clustering in Green Heterogeneous Wireless Networks (cont.)

How Can We Solve It Efficiency?

• Local-Search Based Multi-cell Clustering (LSMC)

  • The algorithm requires an initial solution for local search.

• Form clusters for each UE simply based on the channel coefficient.

• Local search begins, keep finding improving local moves.

科技部資訊工程/智慧計算學門業務說明 (cont.)

對計劃提案之觀察

• 常犯錯誤

  • 取自己發表過的文章、主持人專長不符

  • 中英文夾雜、無頁碼、圖片/數學式字體不一, etc.

• ​可能選項

  • 優先順序、經費額度 (合理性)、申請輔助之設備, etc.

計畫應強調可行性

Hope is not strategy!
