Abstract:
|
In this paper, we investigate the problem of cross-layer design of the link scheduling, frequency assignment and flow control in hybrid terrestrial-satellite wireless backhauling networks. Considering network limitations and requirements, the target is to maximize the traffic that can be delivered by the network in a given period of time by deciding the active backhauling links that can transmit simultaneously over the different frequencies as well as the amount of traffic that should be forwarded in these active links. Due to the interference between the different links, the problem is NP-hard and an efficient scheme is developed to estimate the interference, determine the link capacity lower bound, and obtain the final allocation. The proposed algorithm is simulated in a realistic topology and assuming parameters of practical interest to reveal the advantage of the developed scheme. |
