Abstract

In recent years, Network Coding (NC) draws a lot of attentions because of its ability to improve the network throughput and enhance the network robustness and security. Some systems using network coding have been built. In this paper, we study collisions in wireless network coding system - COPE. Collisions introduced by network coding can be classified into two types, CodIng node Side Collision (CISC) and Receiver Side Collision (RISC). Then, we analyze the collision probability in different scenarios. To reduce CISC and RISC, we propose Collision Avoidance in Network coding (CAN). Our simulation results show that CAN can reduce the collision ratio significantly.
