🧭 Sensors

• Current trend is that transistors are getting much smaller
• CPU speedup is proportional to $\sqrt{\text{num. transistors on die}}$ (i.e. in the hardware)

Advancements in technology depends on the following three components:

Hardware

OS and protocols

Software and Applications

😓 Challenges

Bottleneck in Technology

• Advancements are faster in data technology > storage > CPU > communication > battery
• What this means is that battery technology has been more or less the same for the past couple decades, we ned to design sensors with this in mind (prioritize the technology with slowest growth)

Self-sufficiency

• Sensors can be hosted in hostile environments like battlefields and forests with wildlife
• They need to be self-organizing, managing, self-healing, and scalable (number of messages should scale with number of nodes)
