Introduction
• As the power consumption issue is getting important, wise power control system is needed.
• Smart Grid: A smart, self-healing electric power system. [1]
• Despite of the development of Smart Grid, there lacks a general mechanism.
• We utilize SIP and SNMP as management mechanisms in Smart Grid.

Introduction Cont.
• Most of managing interfaces are still proprietary.[2]
• As Smart Grid becomes an important issue, we need a efficient and general solution.[3]
• SNMP has been widely used in network management, SIP is newbie in this field, however, some people take SIP as the clear choice for Smart Grid communication.[4]

Introduction Cont.
• NAT is the issue in the remote management. [5]– SNMP has no register, hence, SNMP request will
be blocked by NAT if SNMP server is in remote network.
– SIP provides register, thus, end-devices register to the remote SIP proxy server and user agent can send request to end-devices via SIP proxy server.

Introduction Cont.
• Smart Grid management is a new field to SNMP and SIP, evaluate the advantage and disadvantage of these two management mechanisms are needed.

Background Knowledge
• Internet Protocol– IPv4
– Ipv6
• Simple Network Management Protocol (SNMP)
• Session Initiation Protocol (SIP)

Background Knowledge Cont.
• SNMP– Management Information Base (MIB)
– Object Identifier (OID)• Ex: sysUptime:1.3.6.1.2.1.1.3
• SIP– Instant Message ( SIP for Instant Messaging and
Presence Leveraging Extensions, SIMPLE)

System Architecture
• Smart Grid is two-way communication between the consumers and suppliers, in order to achieve two-way communication, this thesis design a small Smart Grid.
• Consumers is available to communicate end-devices with mobile devices, and end-devices send back information to consumers or suppliers for analysis.

System Architecture Cont.

• We porting SIP and SNMP onto end-devices, design several events that will be used in Smart Grid network management.
• Evaluate the performances of two protocols and analyze the differences between two different protocols.
• In this thesis provides the evidences of network management in Smart Grid.

Implementation
• DMA-2440L Platform Porting– Samsung ARM9 Series, S3C2440 Processor
– Kernel: Linux 2.6.24• Enable IPv6: #make menuconfig
– File System: Cramfs• Using Busybox builds Cramfs file system
– Cross compile: Using cross compiler cross compiles the libraries and programs, including SIP and SNMP.

Experiment
• SNMP and SIP can do the same things– Uptime
– MAC
– System Description
• Evaluate the performance of packets transmission– Limited time: Evaluate how much requests of SIP
and SNMP can be sent in limited time.

Experiment Results
• SNMP– Advantage: Small packet size
– Disadvantages: Hard to read OID, NAT traversal
• SIP– Advantages: Easy to read contents message, no
NAT traversal problem, better scalability
– Disadvantages: Heavy packet size

Conclusion
• Despite the rapid growth of Smart Grid, without a general management mechanism slows down the development.
• Both SNMP and SIP are mature protocols in their original design concept.
• In this thesis introduces two feasible mechanisms in Smart Grid management.

Conclusion Cont.
• In the last part of this research, providing the following information– Evaluation of performance
– Advantage
– Disadvantage

Future Work
• Stream Control Transmission Protocol (SCTP) support– SIP is available
– SNMP is unavailable
• Compression the heavy header of SIP will provide an efficient mechanism.

Smart Grid
• Like the power grid, the smart grid also delivers electricity from suppliers to consumers.
• However, it uses two–way digital technology to support communication between consumers and suppliers.
• It combines power systems, telecommunications, smart energy devices, information technology, and digital control.
