Distributed Power Control <strong>and</strong> Rate <strong>Ad</strong>aptation 301TABLE 6.9.2Selected Burst Size u*Po(k) x(k) 0.001 0.010 0.050 0.10054321012345678910Problem 6.9.2: Using Equation 6.60, calculate the burst size u* forvarying power levels, Po(k), <strong>and</strong> queue utilization error, x(k). Fillin the Table 6.9.2. Assume the outgoing flow, w(k), to be equal to2 packets per second (Note: 2 means that there will be 2 packetsdequeued.)Section 6.10Problem 6.10.1: Evaluate the dynamic-programming-based rate adaptationscheme for a r<strong>and</strong>om topology consisting of 150 nodes<strong>and</strong> 1000 nodes. Use the parameters from Section 6.10.1. Plotthroughput <strong>and</strong> energy-efficiency as a function of time.
