sensors
• Application-specific
Network protocols and applications are in a package - difficult
to change or add new applications
• Static configuration
Difficult to change configuration after deployment: e.g.,
sensor data tx rate, reliability, security-level, access control

• Commands for status monitoring (e.g., sampling rate, tx rate,
current reading, power-level), reconfiguration
• Sensor admin can send control commands in two ways:
• 1. via sink server (sink acts as a security hub, common control)
• 2. directly (by using HIMALIS secure communication)

Related standards and potential new topics
Related standards:
ITU-T Y.3001 (FN objectives and design goals),
ITU-T Y.3031 (ID-based communication framework in FN),
ITU-T Y.3032 (ID and locator mapping mechanism in FN),
ITU-T Y.2221 (USN application and services requirements),
IEEE 1888 (sensor data storage format)
Potential new topics for standardization:
1. Interfaces between sensing, computation and
communication units
2. Light-weight authentication and access control methods for
mobile sensors
3. Methods for ID-based communication in heterogeneous
network protocols, e.g., extension to ITU-T Y.FN-heteronet
