With the development of Wireless Sensor Network (WSN) or Adhoc/Mesh, and the design of integrated information network, this project try to focus our research on Adhoc/Mesh channel modeling in three dimensional spatial domain, revealed the key characteristics of wireless channel with IEEE802.11/802.16 frequencies and in indoor/outdoor environments. Developed the Adhoc/Mesh channel models which are more precise and realistic, and with the asymmetric and irregularity; Due to the restrictions on energy and the compact design in sensor network nodes, developed the MIMO channel model in considering the vector sensor and the cross coupling between antennas for Adhoc/Mesh systems; Developed the new measurement and simulating technologies for realizing the simulation for MAC and routing protocols at the considering of the realistic channel model in Adhoc/Mesh systems；With the requirements of meteorological data acquisition, we will design and develop the meteorological skymesh experiment network. This study will form complete theories of Adhoc/Mesh channel models, developed the new simulation technologies for MAC and routing protocols, all research results have original in the wireless channel theory and key applications.
