In IEEE 802.11 MANET, mobile nodes can communicate with each other by multi-hop relaying without any infrastructure, in which all nodes share a common channel. However, increasing the number of mobile nodes significantly degrades the performance, due to shared channel congestion. Hence, the multi-channel approaches have been proposed to scatter network traffic over non-overlapping channels. This work presents a novel multiple channel transmission method, called concurrent multi-channel transmission (CMCT). CMCT guarantees that the data packet transmissions are collision-free, and can be sent concurrently on different channels.
