Research On The Problem Of User Access In The New Wireless Network

Context-aware technology is derived from pervasive computing, it has been applied in various fields, with this technology, the current situation can be perceived through the sensor device. User access problem is the key point when allocating resource in wireless network. In order to solve this problem, matching theory has been used and became a trend, but weighing and evaluating the complex environmental factors are very difficult, therefore, we use context-aware technology to crack this dilemma in the heterogeneous, dense and community networks.First, in the new cellular networks, we present a user and base station matching algorithm based on the context-aware technology, which create the preference function in view of the urgency of uses, the quality of service requirements and other contexts obtained by fuzzy mathematical model in order to achieve user access in the networks.Secondly, in the new social networks, we spectrally divide the resource blocks, using the strength of the association matrix to select service node and previously cache the popular content in service node. In order to achieve matching algorithm in social networks, we exploit use the community attributes to define preference function of resource blocks and users.Finally, simulation experiment and analysis is presented in cellular network and social network.
