บทคัดย่อ
In this paper, we present a cellular wireless network topology design for reliability by considering network link restoration. This is to provide a back up path for any single link failure in a traditional network design with tree topology, so that a network link failure can no longer interrupt the network services and causes the network to fail. As a consequence, the network link restoration approach can greatly enhance the network reliability and quality of services. We adopt a two-phase network design approach. The first phase provides a minimumcost initial network design. The problem is to find a minimumcost network topology which includes selecting the location and type of base station controllers and mobile switching controllers as well as their link types. In the second phase, we provide network link restoration to the minimum cost network topology from phase one in order to improve network reliability. We apply a genetic algorithm (GA) to minimize the cost of the design problem, including the cost of network links, equipment and their installation. GA is used as a meta-heuristic technique for obtaining good solution for the design problem. Various sizes of network design problem are considered and discussed. The GA results are evaluated with those from a brute force search algorithm. ฉ 2008 ICQR.
