Design Flow
Bridging to Implementation
Communication Protocol
System requirements Delay Traffic
Capture these specifications and produce a
set of constraints on LATENCY, ERROR RATES,
SENSING, COMPUTATION
Allow user to describe the network in terms of
logical components queries and services (as in
SNSP)
HW Platform Library MICA Dust PicoRadio

Bridging Application with Implementation
Example SERAN
Three types of Logical Components Virtual
Controller, Virtual Sensor, Virtual
Actuator Connections From VC to VS From VC to
VA Tokens Queries, Commands i.e. Give me
humidity data sampled at a rate R, from time T1
to time T2. Return data within L seconds with a
message error rate P

Iterative Refinement

• Sensing, Computation, Communication
• Satisfy constraints
• Optimize for energy consumption
• Orthogonalization of concerns
• Iterative refinement
• Start from a valid solution
• Centralized computation
• Optimized communication
• Decentralize Computation
• Optimize Communication

Applications

• Ambient Intelligence
• CEC

Environmental Monitoring

• Universal independent on the Implementation on
  any present and future Sensor Network Platform
• Service-based standard set of Services and
  Interface Primitives available to Applications
• Analogy with Internet Sockets

• Environmental Monitoring
• Irrigation
• Water pollution
