摘要：A mobile ad hoc network (MANET) is a wireless network which comprise of mobile computing devicesfor wireless communication, without the help of existing infrastructure. How to take advantage of multiple channels inMANETs poses a serious challenging problem. A more efficient schedule in multichannel systems may be obtained bytreating all the transmission slots on all channels as a two-dimensional (time and frequency) transmission schedulingproblem. Few multichannel transmission protocols such as Collision-Avoidance Transmission Scheduling (CATS)have been proposed to harvest the advantage of high transmission efficiency when multiple channels are deployed.Although such protocols do provide ways to coordinate the use of multiple channels, there exist some serious problemssuch as the throughput fast drop-off under heavy traffic loads. This paper presents a new protocol, namely,MultichAnnel Time-Spread Scheduling (MATS), which attempts to tackle these problems. In MATS, nodes withtransmission requests are divided into three groups, which carry out channel reservations in parallel and cansimultaneously support unicasting, multicasting and broadcasting at the link level. MATS ensures successful andcollision-free data transmissions using the reserved channels and allows multicasting and broadcasting high prioritiesover unicasting.
