Abstract

The advanced wireless sensor networks constitute one of the promising application areas of the recently developed wireless sensor networking techniques. It contains two parts: the terrestrial wireless sensor networks (WSN) and the underground wireless sensor networks (WUSN). The main difference between the hybrid WSN and the conventional wireless sensor networks is the aspect of WUSN, which communicates in the soil. The terrestrial WSN suffer from intensive human involvement and delay of information. There lacks a coherent system that coordinates various technologies including the terrestrial and underground sensor networks to improve the system. In this paper, the hybrid wireless sensor network architecture for agriculture information system is introduced. The framework to deploy and operate the hybrid WSN is developed. Based on the framework, research tests and results are discussed.

Key words: Hybrid wireless sensor networks (WSN), information collection, agriculture, wireless underground sensor networks (WUSN), monitoring.
