Enhanced controller of mobility for a new generation of mobile laboratory

This paper proposes ways to make sure that the components of a mobile laboratory are always connected to various Internet access points anytime, anywhere and where ubiquitous heterogeneous wireless systems are available. A joint mixture of dynamic and automatic wireless, heterogeneous and pervasive intercommunication system is then provided to a mobile laboratory. To achieve this goal, a central node is able to access multiple wireless networks simultaneously and it selects the best network among the wireless networks available nearby. Thus, the limiting system´s low throughput can be overcome when 3G WLAN coverage is available. When the mobile laboratory moves out of the WLAN coverage area, it can be connected to 3G superimposed. Similarly, a satellite network can be used when neither 3G nor a WLAN is available. A strategic Handoff decision and network selection are made to provide a Handoff for our mobile Laboratory. This Handoff decision system is based on fuzzy logic and Multiple Attribute Decision Making (MADM) methods including an extension of the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) with interval data.
