Abstract
In recent years, wireless networks have grown rapidly and 802.11a/b/g technologies have been widely employed. Many telecom operators, universities and households deploy their own wireless access points. Because of the short coverage of WLAN access points and the high operating cost, telecom operators in different countries often establish business relationship to form roaming alliances and then their users can roam to wireless networks of different operators. In Taiwan, main universities have formed a roaming alliance to help their teachers and students to enjoy roaming service at other campus. However, there exist business cooperation problems between campus networks and operators’ wireless networks, so that at this stage campus users still cannot roam to hot spots owned by business operators and vice versa. This research aims to establish a credit system between campus networks and operators’ networks to resolve the problems above. Each wireless network system can categorize their users into original users, and then employ the Game Theory to provide different users with appropriate transmission rates. This research proposes to use utility function to reflect the satisfaction level and analyze the results of roaming agreement by means of simulation. Also, the impact factor, such as advertising benefit and operation models, are also included in the feasibility study of roaming agreement. We hope this research can be instrumental to the establishment of wireless network roaming agreement and improves network resource efficiency in the long term.
