Chapter 5 performs a simulative evaluation of mobile ip via ns - 2 for a scenario comprising of one home agent and two foreign agents based on ieee 802. 11 wireless lan standard. we describe a model which is adaptive to directional motion such as high speed vehicle. we represent the bandwidth and loss packet under constant bit rate ( cbr ) traffic
本模型的主要特點是考慮了定向運動下諸如列車上的專用網路，移動節點在進行大流量通信下切換時的帶寬和丟包數的性能評估，並分析了丟包數和網路時延/移動速度之間的關系，獲得了相應的結論。 -
Future mobile communications have to support the transmission of high rate data and multimedia applications in the radio spectrum, which is already extremely scarce. the basic idea of adaptive coded modulation is to maintain a constant throughput by varying the transmitted power level, symbol transmission rate, constellation size, coding rate or any combination of these parameters. thus, without sacrificing bit - error rate ( ber ), these schemes provide high average spectral efficiency by transmitting at high speeds under favorable channel conditions, and reducing throughput as the channel degrades
自適應編碼調制（ adaptivecodedmodulation ， acm ）的基本思想是在不犧牲系統傳輸性能（比如ber ）為代價的前提下，通過單獨改變發送功率、波特率、編碼方案、碼率、調制方式，或者是綜合改變前面所述的各種參數，在有利的通道條件下，獲得較大的吞吐量，當通道質量下將時，相應地降低傳輸速率，最終達到提高平均頻譜效率的目的。 -
