Abstract:	本文主要是在探討以分碼多工(code-division multiple-access, CDMA)架構為基礎之無線感測網路(wireless sensor networks)連接性(connectivity)效能。我們針對三種不同的感測網路拓撲(topology) :六邊形(hexagonal)、四邊形(格子狀)(Grid)及三邊形(triangular)，探討其布置(deployment)位置呈高斯分布(Gaussian distribution)之變動(variation)時，網路之連接性效能。由模擬結果可知，當設計展頻碼使最低SIR需求達SIR0=-11dB時，變動量較小時(Sigma_N =<0.07)，三種網路拓撲之網路連結性均可達3-連結性。 In this paper, we investigate the connectivity of the CDMA-based wireless sensor networks. The variations of deployment (VD) are model by 2D Gaussion distribution with zero-mean for the triangular, grid and hexagonal topologies. Then, the k-connectivity is studied through the outage probability of the CDMA signal link. Simulation results show that with a minimum requirements SIR0=-11dB, the three topologies can perform 3-connectivity for small variation sN ￡ 0.07.
