On Channel Allocation of Directional Wireless Networks Using Multiple Channels
نویسندگان
چکیده
This paper investigates the channel allocation problem in multi-channel wireless networks with directional antennas. In particular, we propose a general analytical framework on the number of channels, in which we consider a new directional antenna model. This antenna model is more general than existing antenna models since other existing antenna models can be regarded as a special case of our model. Besides, it can accurately depict directional antenna with consideration of side-lobes and back-lobes. Moreover, we derive the upper bounds on the number of channels of such networks to ensure collision-free communications. Our results are also insightful to the network design and network deployment.

This paper concerns sub-channel allocation in multi-user wireless networks with a view to increasing the network throughput. It is assumed there are some sub-channels to be equally divided among active links, such that the total sum rate increases, where it is assumed each link is subject to a maximum transmit power constraint. This problem is found to be a non-convex optimization problem and i...
