Wireless Mesh + TV White Space

Thesis modeling sub-GHz TV White Space wireless mesh links to extend reliable connectivity over mountainous and obstructed rural terrain.

Traceroute path · 5 hops

Each hop isolates problem, constraints, architecture decisions, verification artifacts, and limits.

- Examines whether multi-hop wireless mesh relaying over UHF TV White Space bands maintains usable link margins across non-line-of-sight valley topologies.
Next hop follows below
- Secondary mesh nodes must detect and avoid channels occupied by licensed DTT broadcasts.
- Topology must handle varying inter-node distances, altitude deltas, thermal noise, and intermittent mobility.
Next hop follows below
- Completed literature review comparing reactive and proactive mesh routing protocols in sparse deployments.
- Implemented MATLAB terrain simulation sweeping transmit power, node count, and noise against throughput, latency, and RSSI.
- Implemented coexistence simulation balancing base-station and secondary node allocations alongside incumbent TV channels.
Structural schematic · Illustrative (not measured telemetry)
Illustrative ridgeline relay geometry (structural diagram only, not simulation measurements).
Next hop follows below
- No numerical throughput, latency, or BER figures are published here prior to thesis approval.
- Results remain MATLAB simulation only — no outdoor RF hardware testbed has been built yet.
Asset status (diagram): MATLAB plots withheld pending faculty thesis review (GAP-08).
Next hop follows below
- Incorporate advisor feedback and compare AODV vs OLSR overhead under identical ridgeline path-loss conditions.
