Abstract: With the developing of ubiquitous computing,the integration of software and hardware has become an important trend of personal consumer electronics field,and wearable devices are becoming the current research hotspot of academic and industry．Most of these devices have certain capabilities of sensing,computing and service．But now interface of wearable devices is different from each other,and the capability of collaboration is weak,which causes the waste of sensing and computing capabilities,also can not provide rich services．To solve this problem,this paper proposed a mobile middleware for collaboration of data and services between wearable devices-Scudware Mobile．Scudware Mobile aggregates data and services of wearable devices,and provides a unified interface of accessing to the application layer．Also we introduced collaboration mechanism into Scudware Mobile．Using Scudware Mobile,we implemented two applications:portal of personal data and shaking e-card.

Key words: Scudware mobile,Collaboration of data and services,Wearable device,Smart mobile
