In mobile environment, the computing capacity of the equipment in users' hands becomes more and more powerful. The smart phones and the wireless network cards provided by the communication enterprises, make it possible for people to access the resources in the network. The 3G technology has improved the network speed and quality. The computers with a ralph lauren polo shirts 3G netcard become more and more popular. Along with the progress in terminal's computing ability and network quality, people request that pervasive computing be realized. However, in mobile environments several problems still exist. First, the range of people's Lacoste Polo Shirts mobility is big. When people move to a new place, often he can no longer use the original services in the old place. How to make it possible that people can use the services in the new place to complete their nike shox shoes tasks without too much distraction from their main job is a very difficult problem. That concerns the application migration in mobile environments. Second, in mobile environments, the bandwidth of the smart equipment is usually limited and unstable. In this situation, the speed of service discovery process cheap wedding dresses 2010 may be low. Current algorithms for service discovery can not work very well.Taking the pervasive computing application in mobile environments as the background, this paper discussed the problems cheap white wedding dresses 2010 existing in pervasive computing in mobile environments, introduced a proper service discovery algorithm, established an application migration model in mobile environments.
