Wireless Sensor Networks
Choose the right WSN foundation, deployment, routing, coverage, tracking, or mobility chapter
Your guide: Packet Pete
“A packet you can’t trace is a claim you can’t defend — name the address, the route, and the hop that dropped it.”
Start With the Field Story
Start with a field team that knows something must be sensed, but has not yet proven where nodes can live, how long they can run, or how readings will reach an owner. Use this module as a decision route: name the sensing promise first, then follow energy, coverage, routing, tracking, mobility, and maintenance evidence until the WSN design can be reviewed without guesswork.
This page is the route map for the Wireless Sensor Networks module. Use it when you need to find the right chapter for a design question, not as a replacement for the sidebar. A WSN decision usually starts with the sensing goal, then checks power, placement, coverage, communication, routing, mobility, and maintenance evidence.
Learning Objectives
By the end of this index, you should be able to:
- Choose a starting chapter from the evidence you already have: sensing goal, field environment, energy budget, coverage requirement, traffic pattern, or mobility pattern.
- Separate WSN foundations from deployment, coverage, routing, tracking, and mobility topics.
- Explain why energy, communication, and maintenance evidence must be reviewed together in a WSN design.
- Record a WSN decision without relying on a fixed chapter count or a generic “read everything” path.

Evidence Loop
A useful WSN route leaves behind the reason for the route choice. Capture the evidence before optimizing algorithms or choosing a technology.
- Measured phenomenon, required location, and acceptable sampling interval
- Sensor accuracy, drift, calibration, enclosure, and placement constraints
- What missed, delayed, or false readings would mean operationally
- Gateway location, traffic direction, hop count, link quality, and interference
- Coverage model, redundancy requirement, barriers, and deployment access
- Protocol assumptions, routing behavior, and recovery after node loss
- Battery or power source, duty cycle, replacement interval, and access effort
- Ownership of firmware, keys, gateway configuration, and monitoring alerts
- Retest triggers after enclosure, placement, firmware, traffic, or site changes
Minimum WSN decision record: sensing goal, field environment, node role, power assumption, coverage assumption, communication path, routing or collection behavior, observed test result, accepted tradeoff, owner, and retest trigger.

Common Pitfalls
- Choosing a protocol before defining the sensing goal, field environment, and maintenance interval.
- Treating battery life as a single number instead of a duty-cycle, traffic, temperature, and access assumption.
- Reviewing coverage without checking whether the same nodes can communicate with the gateway or relay path.
- Optimizing routing while ignoring placement, enclosure, interference, link asymmetry, or gateway ownership.
- Using tracking or mobility chapters when the unresolved issue is ordinary deployment, energy, or coverage evidence.
- Keeping a route map tied to a brittle chapter count rather than to durable learning lanes.
Summary
Wireless Sensor Networks connect distributed sensing, constrained nodes, low-power communication, coverage, routing, tracking, and operations. Use this route map to select the chapter group that matches the current evidence gap. Start with foundations when the WSN model is unclear, deployment and coverage when placement is uncertain, energy chapters when battery and duty-cycle assumptions dominate, routing chapters when data paths or aggregation matter, tracking chapters when location over time is the problem, and mobility chapters when devices or data collectors move.
