Interference characteristic simulation in CSMA/CA-based wireless multi-hop networks


Abstract:
Conflict interference is one of the key factors affecting the performance of wireless multi-hop network. In view of the different distribution of interference nodes in the network, adopting stochastic point process simulation, the cumulative interference characteristics of nodes were studied based on different stochastic point processes in Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) protocol. Then the interference simulation platform based on NS2 was established to simulate the realistic interference distribution. Finally, the comparison between them shows that there is a certain difference between the simulation and the reality, and the reasons were also pointed out.
