Integration and deployment of IEEE 802.15.4 wireless sensor networks with a wireless mesh backhaul network

Abstract

This paper describes the deployment of a IEEE802.15.4 Wireless Sensor Network (WSN) in a campus network and integration with IEEE 802.11a/g Wireless Mesh Network (WMN) for the backhaul. The first problem discussed is the integration of the WSN with the WMN. This research utilises the Motorola IAP4300 - Intelligent Access Point for its WMN backhaul communication and the Crossbow MIB600 Ethernet gateway and MPR2400-MICAz for the WSN. Secondly it explores the issue of coexistence between IEE802.11g and IEEE802.15.4 that is utilising the same industrial, scientific and medical (ISM) radio band of 2.4GHz. This paper describes our deployment and integration experience and provides results which will be of interest to industry and research professionals.
