CRAWDAD is a community-maintained archive and directory of real‑world wireless network data, traces, and related datasets (such as pcap files). It catalogs datasets from multiple contributors to support reproducible research in wireless and mobile networking.

Overview of This Dataset: due/packet-delivery

Wireless sensor network (WSN) link performance dataset collected indoors over 6 months, covering:

• ~50,000 parameter configurations for 7 key protocol stack parameters
• Meta‑data for nearly 200 million transmitted packets
• 4 major performance metrics: energy, throughput, delay, loss

Key metadata:

• Measurement period: 2012‑11‑01 to 2013‑11‑30
• Release date: 2015‑03‑30
• Last modified: 2015‑03‑30
• DOI: https://dx.doi.org/10.15783/C7NP4Z

Environment & Methodology

Collection Environment

• Location: Long hallway in a university building
• Dimensions: 2 m × 40 m
• Node mounting height: 0.7 m (wooden stands)
• Line-of-sight maintained between two motes
• Sender–receiver distances: 10, 15, 20, 25, 30, 35 m
• Human presence: Students and employees may walk in the hallway during experiments

Network Configuration Parameters

For each experiment, the following parameters are varied:

• Packet inter‑arrival time (ms): 10, 15, 20, 25, 30, 35, 40, 50
• Packet payload size (bytes): 20, 35, 50, 65, 80, 95, 110
• Maximum queue size (packets): 1, 30, 60
• Max_tries (max transmissions): 1, 3, 5
• Retry delay (ms): 30, 60
• Transmission power level: 3, 7, 11, 15, 19, 23, 27, 31
• Distance (m): 10, 15, 20, 25, 30, 35

Data Collection Methodology

• Metadata of each packet recorded at sender and receiver nodes
• Data forwarded via USB cables to a laptop
• Contains no sensitive or personal information → no sanitization performed

Traceset: due/packet-delivery/delay

Per‑packet delay measurements under various stack parameter configurations.

Example Trace: 10meter

• Content: Delay measurements of all packets transmitted at 10 m
• Format:
  • Each file has 8064 lines
  • Each line corresponds to one stack parameter configuration
  • Line structure:
    • period | packet length | queue_size | max_retries | retry_delay | TxP_level | distance | average_SNR | delay_run1_pkt1 | ... | delay_run1_pkt300 | delay_run2_pkt1 | ... | delay_run2_pkt300 | ... | delay_runN_pkt1 | ... | delay_runN_pkt300
  • Special values:
    • 9999 or 1111 indicate packets not received or delay measurement errors
