Integrated Solutions
■ Chipcon CC2430■ Ember EM250■ Jennic, Atmel, etc…
► ~$5► Better performance
■ But…► 8051► XAP2► Steep learning curve
and NRE requirements

Need easy development
■ Minimum HW Development■ Robust software infrastructure
►Include services AND networking►Instrumentation and Feedback Predictable
■ Applicability over multiple generations of hardware – write applications only once►SP link abstraction►Hardware Abstraction Architecture (HAA)

What about TinyOS 2?
■ When will it be released???■ No reliability metrics■ No test & verification framework■ Must recompile (potentially rewrite) apps as
hardware and networking technologies change■ No driving commercial entity■ Companies very cautious to embrace
► Crossbow, Moteiv, etc► Need to support TinyOS 1.x customers► Doesn’t solve the ease-of-use issue

Boomerang by Moteiv
■ Moteiv’s TinyOS distribution■ Includes
► Low power mesh• Temporal and Spatial diversity• Frequency diversity coming soon
► Time synchronization► Wireless reprogramming► T2 Timers, Resources, Scheduler, Flash► Includes SP, HAA, DMA► Backwards compatible with TinyOS 1.x applications

Tmote Invent
■ Innovative Design■ Integrated Sensors
► Accelerometer, Speaker, Microphone, Human-visible Light sensor
■ User Interface and Feedback► LEDs, Buttons
■ Rechargeable■ Includes Boomerang,
Moteiv tested and certified distribution of TinyOS

Prognostications (I)
■ TI acquired Chipcon► Chipcon CC2420 + TI MSP430 solution► Low cost, familiar architecture
■ Extended memory devices ► ~1MB address space
■ Chips ship with networking stacks as a commodity► Lots of networking options
• Zigbee, TinyOS, SmartMesh, MeshScape, XMesh, etc► Want to use the best networking for the
app/environment

Open Items
■ How to build powerful applications easily, quickly, faster, reliably, predictably?► Kernel hacking TinyOS► Knob tuning Vertically integrated solutions► Is there a middle ground that provides enough
flexibility and configuration at small learning curve?■ How to leverage available technologies?
► New hardware solutions► Multiple networking solutions (TinyOS or non-TinyOS)
■ How to enable new classes of applications?

Prognostications (II)
■ Next 18-24 months define how customers view wireless sensing as a valuable technology
■ Potential hype vs feasibility ala RFID► Lifetime – Is 10+ years possible on AA batteries?► Scale – Let’s get past the 250 to 1000 node limit.► Latency – Control guys very concerned.► Reliability – Remember X10?
■ Must embrace standards as an option► Zigbee in TinyOS, Z-Wave, etc► Multiple vendors/suppliers reduce customer fear
■ Time to move beyond monitoring networks
