Abstract

The paper focuses on the performance analysis of channel assignment algorithms for peer to peer wireless ad hoc network by means of realistic channel model. The channel assignment is modeled as an edge colouring problem and two colouring algorithms including random and greedy colouring have been studied using the realistic 3D ray tracing based path loss model and its performance is compared with the theoretical model. The simulation study shows that the algorithms perform better with the ray tracer model with around 10 dB improvement in SINR as compared to the theoretical model.

点对点无线自组网中信道分配算法的性能研究
本文利用真实信道模型对点对点无线自组网信道分配算法进行了性能分析。将通道分配建模为边缘着色问题,采用基于真实三维光线追踪的路径损失模型,研究了随机着色和贪婪着色两种着色算法,并与理论模型进行了性能比较。仿真研究表明,与理论模型相比,该算法在射线追踪器模型下的信噪比提高了约10 dB。
