Performance study of channel assignment algorithms in peer to peer wireless ad hoc networks

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.
