An awareness algorithm to discover service nodes is proposed to deal with the problem of data-awareness and data-transmit in both time and space in mobility-aware of Internet of Things(IoT)
which is caused by nodes mobility and random. The algorithm bases on social relations cognition
and quantizes the social relation of all nodes by introducing interconnection factor and distance factor. Then
cohesive subgroups and a node-mobile probability table are constructed to predict the trace of mobile nodes. Finally
awareness service nodes in the objective regions are determined through trust-transference and probability tree calculation. Simulation experiments show that the proposed method effectively reduces both the shortest distance among mobile nodes and the network average distance
improves the way of date acquisition and increases the quality of awareness service in IoT.
