摘要: This article provides an overview on the topic of ad hoc network performance analysis, mainly from a physical layer standpoint. The emphasis paper is how individual link and can be evaluated in analytically tractable manner, such that design insights obtained optimization over key parameters possible. Our model large random network, where wireless channel comprises path-loss fading. Various factors are taken into account: multiple-access (MA) scheme, as direct-sequence (DS) CDMA frequency-hopping (FH) CDMA; error correction coding Reed-Solomon (RS) or convolutional coding; coherent noncoherent detection; use multiple-input, multiple-output (MIMO) techniques to enhance protection increase transmission rate. optimized terms useful metrics throughput, information efficiency capacity.
