....in other directions can communicate concurrently without interfering each other. These two approaches improve the throughput by increasing spatial reuse, but still they use only a single channel. The approach in this paper, is to achieve improved performance using multiple channels [6] 7] [8], 9] 10] Data transmitted in different channels do not interfere with each other, thus can take place in the same region simultaneously. So the throughput can increase significantly, proportional to number of channels in ideal case. Although not studied in this paper, having multiple channels ....

....the number of channels is large, the control channel can become a bottleneck and prevent data channels from being fully utilized. 9] mentions that if every control packet has a length of L c and data packet length is L d , maximum number of channels should be no more than L d =3L c . Jain et al. [8] propose a protocol that uses similar scheme as [9] in having one control channel and N data channels, but selects the best channel according to the channel condition at the receiver side. By intelligently selecting the data channel, it achieves throughput improvements, but still has the same ....

....since the minimum power required to maintain connectivity is used in the Ad hoc mode, performance can degrade heavily under mobility. Variable power has been investigated in Ad hoc networks in PCMA, a medium access protocol, proposed in [16] The use of multiple channels has been considered in [15]. These MAC protocols are a deviation from IEEE 802.11 and requires changes in the 802.11 protocol, a widely used standard. Moreover, they do not address the issue of routing when variable powers or multiple channels are used. The SCN architecture has been extended with a variety of techniques, ....
