1. IoT and M2M Concepts Structural Aspects, Key Technologies, DAG & DODAG, and 3GPP Architecture

2. Structural Aspects of IoT Environmental Characteristics: - Low power, low cost - More devices than LAN - Limited code and RAM Traffic Characteristics: - Different from traditional networks - Communication has specific length & volume Scalability: - Larger systems must be more efficient Interoperability: - Standards enable cost-effective deployment Security & Privacy: - Ensuring confidentiality, integrity, trust Open Architecture: - Supports multiple applications over a common platform

3. Key Technologies of IoT - Device Intelligence - Communication Capability (IP, TCP/IP) - Mobility Support - Device Power (Battery & Self-Energizing) - Sensor Technology (Sensing, Computing, Communication)

4. Smart Cards vs. RFID Tags Smart Cards: - Microprocessor for computation & security - Mutual authentication & large storage - Short-range communication RFID Tags: - Read-only, stores unique ID - One-way authentication - Small memory & longer-range communication - Cost-effective

5. DAG & DODAG in RPL DAG (Directed Acyclic Graph): - No cycles, used in routing DODAG (Destination-Oriented DAG): - Rooted at a single destination RPL (Routing Protocol for Low-Power & Lossy Networks): - Forms paths towards the root - Uses DAG Information Objects (DIO) for route discovery - Uses Destination Advertisements for route propagation

6. M2M in 3GPP Architecture - MTC (Machine-Type Communication) enables device-to-device communication - MTCu: Reference point for 3GPP bearer service - MTCsm: Reference point for SMS-based communication MTC Server Use Cases: 1. Operator-Controlled MTC Server (Within operator's domain) 2. External MTC Server (Outside operator's domain, using network connectivity)
