Assignment Scheme

In this paper, we investigate mechanisms for improving the quality of communications in wireless-optical broadband access networks (WOBAN), which present a promising solution to meet the growing needs for capacity of access networks. This is achieved by using multiple gateways and multi-channel operation along with a routing protocol that effectively reduces the effect of radio interference. We present a joint route and channel assignment scheme with the objective of maximizing the end-to-end probability of success and minimizing the end-to-end delay for all active upstream traffic in the WOBAN. Performance evaluations of the proposed scheme are presented using ns-2 simulations, which show that the proposed scheme improves the network throughput up to three times and reduces the traffic delay by six times in presence of 12 channels and four network interface cards (NICs), compared to a single channel scenario.

Energy Optimizations

The second part of this chapter focuses on deployment practices and describes how different access network architectures can improve the energy consumption, when considering both the telecom equipment and its supporting functions. The authors show that introducing an access network architecture that distributes more functions in the outside plant does not negatively impact energy consumption of the access network. A use case for the Benelux is worked out and a related innovation in the Swisscom access network shows that also in the more centralized architectures further optimizations are possible.1

Research Perspective

For the unsymmetrical bandwidth in HFC network, this paper proposes a data transmission scheme of Cable Modem based on DOCSIS1.1. This scheme can meet different kinds of data’s demands. It can guarantee fine grading data transmission management and low ratio of packet loss. Then, this paper proves the validity of the scheme. Lastly, in order to improve the quality of data transmission, it gives the difficulties and research perspective in the future.
