Currently there is a growing demand towards interactive multi-media services using high capacity Hybrid Fiber Coaxial (HFC) networks. With regards to the realization of upstream traffic, many problems occur with the accumulation of noise due to the tree and branch architecture of the coaxial access network. We have figured out the typical network topology for the two-way HFC network, and pointed out...
Wireless mesh nodes equipping multi-radio interfaces on each node and using multi-channel for transmission can greatly enhance the network performance. In this paper, a genetic algorithm, genetic tabu search, was presented to solve the channel assignment problem. The algorithm was evaluated by simulation on NS2 and compared with greedy and multi-radio unification protocol algorithms. Simulation results...
