A novel service mobility architecture for SIP environments

Lately, the proliferation of small portable devices has driven the introduction of a new mobility concept called service mobility. In order to support service mobility, we introduce a new architecture implementing mechanisms to access end user's personalized services regardless of his physical location. The proposed architecture leverages on mobile agent technology to transport and move services to the end user's registered terminals and the Session Initiation Protocol (SIP) for user location signaling. A decentralized approach purely based on mobile agents is compared with a centralized approach. The performance measurement results show that mobile agents are worth being used for realizing service mobility but in specific conditions
