| Abstract(in English) | Wireless Ad hoc Network offers the advantages of direct communication without infrastructures such as base station. Each node has router function and finds the best relay stations due to the periodic information of other node's location and microwave propagation condition collected by the node of itself. Multihop communication is available, even if microwave cannot reach to the destination. In that case, interference at the same channel can be avoided by setting the directional beam to the desired node and setting the null point of adaptive beam to the undesired node, which contribute the good performance of SDMA (Space Division Multiple Access) in the same network compared with setting omni beam to the other nodes. So, it should be good work to utilize directional beam and adaptive beam with the neighbor node location information. However, GPS (Global Positioning System) information is not always useful because microwave is shielded by buildings or bridges, so that node of itself should acquire the other node's location information in the actual dynamic changing network. And the other node's information of location and received signal level means microwave propagation condition should be considered for the ad hoc network routing protocol. In this paper, we propose the sequential lobing monopulse processing based on AST (Angle-SINR-table) information to determine the node direction, which procedure is the calculation between received signal levels with discriminator equation due to the characteristics of combination through stirred 2 directional beams. And we introduce the experiment results of direction measurement accuracy with static and moving node's behavior in the anechoic chamber and on the field of car parking area. |
