Protocol Comparison Simulator

Compare common IoT communication protocols against the requirements of a deployment. The goal is not to find a universal winner, but to see which protocol fits the current constraints best.

Goal

Select a protocol by matching requirements to tradeoffs, not by choosing the most familiar option.

Try First

Start with Smart Farm. Notice why range and battery weight push the decision toward LPWAN.

Watch

The map, fit scores, stage cards, and recommendation update when priorities change.

Why It Matters

Protocol mistakes show up later as battery failures, coverage gaps, cost surprises, or latency limits.

Deployment Scenario

Choose a deployment pattern.

Protocols To Compare

Select two to four protocols. The model keeps at least two choices active.

Requirement Weights

Environment Stress

Start by stating the deployment requirements. A protocol is only good or bad relative to a job.

Tradeoff Map

Horizontal position shows range fit. Vertical position shows battery fit. Bubble size reflects bandwidth capability. The highlighted bubble is the current best weighted fit.

Recommendation Detail

Choose a scenario to see the recommendation.

Candidate Profiles

These are teaching scores for comparison. Real projects still need standard versions, spectrum rules, module choices, antenna design, and certification checks.

Decision Notes

The model compares fit, not absolute technical maximums. A low score means the current scenario asks for something the protocol is not designed to optimize.

Beginner Ramp

A protocol is a communication method with assumptions about distance, speed, power, topology, cost, and reliability. No single protocol is best for every IoT system.

What Scores Mean

Scores are normalized teaching estimates from 1 to 10. They help compare tradeoffs, but they are not compliance or product-selection data.

Range Warning

Range depends on antennas, buildings, terrain, frequency, gateway placement, regulation, and transmit power. Treat any simple range number as context, not a guarantee.

Protocol Families
  • BLE favors short-range, low-power personal devices.
  • Thread and Zigbee favor low-power mesh networks.
  • Wi-Fi favors high throughput and existing infrastructure.
  • LoRaWAN favors long range and tiny infrequent payloads.
  • Cellular IoT favors wide-area managed connectivity.
  • Ethernet favors wired reliability and low latency.
Decision Rule

Choose the protocol that satisfies hard constraints first. Then optimize softer goals such as module cost, ecosystem, and developer familiarity.

Validation Rule

After a shortlist, validate with link budget, payload size, duty cycle, security model, certification, operational cost, and field testing.

Practice 1

Choose Smart Farm, then raise payload demand. Why does the best choice become less confident?

Practice 2

Choose Wearable Health. Compare BLE and Cellular IoT. Which requirement makes BLE win or lose?

Practice 3

Choose Factory Monitor and increase interference. Why does reliability become more important than raw bandwidth?
