碩士 === 國立成功大學 === 電腦與通信工程研究所 === 102 === We need to think much problem when setting communication system. In recent years, power consumption problem is more important. This thesis discusses power consumption optimization of Ad-Hoc network with timeslots. When we set communication system, considering cross-layer optimization by referring OSI(Open System Interconnection Reference Model) model. The mathematical model associates to power, half-duplex and timeslots. It's a MIFP(Mixed Integer Fractional Programming). We use mathematical skill to relax our model. Such as relaxing integer variable, log term by piecewise-RLT(Reformulation-Linearization Technique) and CCT(Charnes Cooper Transform). Hence our model becomes a LP(linear programming). Finally, we apply CPLEX to solve our problem. According to the result,we discuss the best path and the requiring number of timeslots.
