Geographic routing is an attractive localized scheme for wireless sensor networks (WSNs) due to its desirable scalability and efficiency. Maintaining neighborhood information packet forwarding can achieve a high efficiency in geographic routing, but may not be appropriate WSNs highly dynamic scenarios where network topology changes frequently nodes mobility availability. We propose novel online scheme, called Energy-efficient Beaconless Routing (EBGR), which provide loop-free, fully...

Data aggregation is a widely used technique in wireless sensor networks. The security issues, data confidentiality and integrity, become vital when the network deployed hostile environment. There has been many related work proposed to address these issues. In this paper we survey classify them into two cases: hop-by-hop encrypted end-to-end aggregation. We also propose general frameworks for cases respectively. framework higher computation cost on nodes, but achieves stronger security,...

Session-based recommendation is a challenging problem due to the inherent uncertainty of user behavior and limited historical click information. Latent factors complex dependencies within user’s current session have an important impact on user's main intention, but existing methods do not explicitly consider this point.
