| Abstract: | 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,a... |
