The Impact

Recently applications and technologies utilizing the free industrial, scientific, and medical (ISM) band have grown exponentially. Mainly there are three dominant technologies operating at the ISM 2.4 GHz band, IEEE 802.11 b/g, Bluetooth and IEEE 802.15.4 or Zigbee. With the diverse deployment and broad range of applications running over such technologies, it is inevitable that radio channel interference between devices utilizing such technologies exist. In this chapter we focus on co-existence issues between such technologies and on the quantification of the impact of Bluetooth on IEEE 802.11b/g.

Coexistence Issues

This The IEEE 802.15.4 devices are proposed to operate in the 2.4 GHz industrial, scientific and medical (ISM) band. The other devices that use IEEE 802.11 b, g and n share the same frequency band. The interference caused by these technologies can degrade the performance of an IEEE 802.15.4 based wireless network. In this paper we study such degrading effects on a network equipped with IEEE 802.15.4 devices that is exposed to interference in turn with IEEE 802.11 b, g and n. The performance measure in this paper is the link Packet Receive Rate (PRR). Measurements are performed with real-life equipment, in order to quantify coexistence issues. We test all 16 channels of IEEE 802.15.4 in 2.4G band and the results show the decrease of PRR when suffering in close frequency with IEEE 802.11. The connection between energy detection and PRR is also exhibited in this paper.

In WSN transport, layer protocol plays a significant role in maintaining the node’s energy budget. To find out the dependency of Transport layer on MAC/PHY layer, the authors have extensively tested various transport protocols using IEEE 802.11, IEEE 802.15.4 MAC/PHY protocols for WSN. For IEEE802.11 and IEEE802.15.4 with RTS/CTS ON the TCP variants has shown >80% packet delivery ratio and 5-20% packet loss, while for UDP it is around >63% and 19.54-35.18% respectively. On average 1-3% additional energy is consumed for packet retransmissions in IEEE 802.11 with RTS/CTS OFF whereas significant energy efficiency is observed in IEEE802.15.4 case. For IEEE 802.11 with RTS/CTS ON high throughput, low packet drop rate and increased E-2-E delay is observed, while for IEEE 802.15.4 improved power efficiency and jitter behavior is observed. This has led the foundation for the future development of the cross-layered energy efficient transport protocol for WSN.
