Delay Tolerant Mobile Sensor Network (DT-MSN) possesses high delay tolerability. And the real-time requirement of data is reduced, which results in data packet accumulation. The limitations of nodal buffer and great data accumulation have created data management problem. Thus, it seems particularly important to complete the task of quick analysis of the(More)
The routing efficiency in delay tolerant networks is degraded due to intermittent connection and high latency. Additionally, socially selfish nodes in social networks refuse to provide message forwarding service since there are limited resources. To solve these problems, an improved routing algorithm based on the social link awareness is proposed. In this(More)
Due to the difficulty of getting the association rules over out-of-order streams for big data, a new improved BP algorithm based on dynamic adjustment is proposed. We firstly use a dynamic adaptive structural adjustment mechanism to change the network training structure according to the environmental requirements, which can automatically remove invalid(More)
