| Abstract(in English) | Many location management methods have been proposed so far for the access to information stored in portable computers. As for the performance of these access methods, it has been shown that the efficiency of each method fully depends on a given environment of the system. We first propose an adaptive query processing strategy in the mobile computing environment, in which several location update methods and query processing methods can be dynamically selected. Then, we evaluate a system to see the performance of the adaptive strategy in environments which are scaled by several network parameters, such as the mobility rate of the mobile host, query occurrence rate, and the cost of unicast and multicast of packets, etc. In addition, we show that the adaptive query processing strategy is more efficient than using each method independently. |
