Abstract:

When the mobile devices provide services for a user in ubiquitous stub environment, some service transmission paths will be out of work because of device movement or limited power. The main purpose of the article is to seek a way for quick service recovery and reliable service transmission. This author put forward a dynamic service recovery mechanism which can maintain the data in the service transmission path flexibly. When the service transmission fails, the upstream recovery point directly resends the service data to its downstream recovery point. Simulations show that this mechanism can effectively reduce the request failure probability and the execution time.

Key words: ubiquitous stub environment, recovery, transmission, group
