Wireless Sensor Network Reliability

RF Interference

  • Common interference sources:

    • Multipath interference

      • Occurs when the RF signal interferes with itself

      • Reflections off surfaces of all types

      • Can interfere with original signal and even cancel it out

    • Interference with other transmitters

      • ISM band 2.4 Ghz wireless is increasingly common

      • Signals can be affected by other sources

      • Data slows down (more retries) or even stops

      • A good way to avoid it is to ‘frequency-hop’

  • Examples of other transmitters in the 2.4 GHz band can be WiFi nodes, microwaves, cordless phones, Bluetooth devices, RFID, and other wireless sensor networks.

  • How can it be avoided?

Wireless Sensor Network Reliability

Interference Avoidance

  • Typical methods:

    • Direct Sequence Spread Spectrum (DSSS) modulation

      • Part of the IEEE802.15.4 radio standard

      • Spreads the signal over a wider bandwidth

      • Reduces the chance of blocking the whole signal

    • Frequency-Hopping Spread Spectrum (FHSS) modulation

      • NOT part of the IEEE802.15.4 radio standard

      • Uses a range of base frequencies

      • Transmitter and receiver periodically hop to a new frequency

      • Acts more like a narrowband radio for very short intervals

      • Very unlikely that all channels in the band are interfered

    • Dynamic channel hopping

      • Not a modulation technique

      • Enhances simple FHSS modulation by dynamically detecting persistently busy channels and avoiding them

  • The best mesh radio systems use all three techniques

Wireless Sensor Network Protocols

How do they affect performance?

  • Two main options:

    • Carrier Sense Multiple Access

      • Collision-based protocol

      • Uses collision-avoidance (CA) or collision detection (CD)

      • Most WSN protocols use CA to avoid network overhead

      • Network communication is not time-synchronised

      • Pseudo-random ‘Back-off and re-try’ mechanisms are used

      • Collisions within the network escalate as networks get larger

      • ZigBee is based on this CSMA-CA approach

    • Time Synchronised Protocols

      • These minimise or avoid collisions and transmission re-tries

      • Time synchronisation allows the use of channel-hopping

      • TDMA (Time Division Multiple Access) is an example

      • Also called ‘slotted’ protocols because each device has a ‘time slot’

  • The benefits of synchronised traffic and channel-hopping are:

    • Better performance (fewer collisions/retries)

    • Increased battery life (fewer retries)

    • Better interference avoidance (channel-hopping)

  • The most sophisticated systems use adaptive dynamic channel-hopping

Protocol Standards?

  • 802.15.4-based market offerings are differentiated by proprietary protocol stacks with different design goals

  • Network layers of the protocol

  • are not standardised

  • There are many trade-offs in protocol design

  • There is room for several feature-specific protocol variants using the IEEE 802.15.4 base standard

  • It is important that hardware remains 802.15.4 compliant

  • ‘Standard protocols’, if they ever become available, will not mean that proprietary protocols become obsolete or unnecessary.

  • ZigBee is not a standard and has serious reliability and performance limitations in industrial and commercial environments. ZigBee equipment from different vendors does not interoperate – one of the key goals of a standard.
