3. Introduction Smart grid system: A smart grid is an emerging technology in recent years which combines ordinary electricity networks with digital technology and aims to use electricity more efficiently. Smart meter networks: It is very crucial in the smart grid system which provides two-way communication services between suppliers and customers. 3

4. Introduction (Cont.) Quality of services (QoS) requirements : – There are many different types of messages (control, electrical usage and so forth) are transmitted between suppliers and customers. – Meet QoS requirements (bandwidth, latency and so on) of these messages is very important. Smart meter networks are service-based networks. – Provide good communication services between suppliers and customers. 4

5. Introduction(Cont.) Internet protocol: – It is a popular network technology to implement smart meter networks. – Best-effort service model Can not guarantee to provide stable and reliable services. How to best profile the Internet protocol Suite(IPS) for use in smart meter networks is very important. [1] 5

6. Introduction(Cont.) QoS provisioning: (design the suitable IPS for smart meter networks) – Application layer :Session Initiation Protocol (SIP) SIP functions (subscribe, notify and so forth) – Transport layer: Stream Control Transmission Protocol (SCTP) SCTP functions (multi-homing, multi-streaming and so forth) 6

11. Conclusion My thesis aims to study of transport protocols performance in smart meter networks in order to provide a reference for smart meter networks designers to profile the suitable IPS for their smart meter networks. 11

12. Future works Implement the IPS (SIP/SCTP) in real testbed in order to more understand how it cooperates with heterogeneous smart meter networks and the server on the Internet in the realistic experimental environment. 12
