Abstract: New algorithms were proposed in this paper based on the segment-based policy, in order to detect disconnection in mobile computing environment and update location efficiently. First algorithm uses fix-time policy, can detect disconnection quickly and efficiently, but cause more numbers of location updates. Second algorithm uses adaptive time limit policy and finds a good balance. At last group-based policy will be modified to detect and deal with disconnection. Our experiments show that these algorithms not only decrease numbers of location updates,but also can detect network disconnection efficiently.
