In practical use, data traffic has a feature of high-burst in wireless network, which means that the serve request of a user is not continuous. With full buffer traffic model, network operators can give evaluations on the peak data rate and the least data rate of heavy load network. However, rather than the peak data rate and the least data rate, what attracts users most may sometimes be the typical...
To further increase the experienced data rate per user, and to overcome the poor indoor penetration and the presence of dead-spots, the network architectures with relays, picocells and femtocells underlaying the macrocell network which are commonly referred as heterogeneous networks have drawn more and more researching interests. One of the main challenges of heterogeneous networks is the severe inter-cell...
Viewing the current situation of malicious tampering to the image feature points which are used for detecting, we proposes a Identifier-based scheme that can relocate tampered feature points. The scheme can effectively reconstruct calibration coordinates by examining embed identifiers in several rings around dasiaMRFPpsila (most robust feature points) to eliminate the geometric attacks such as translation,...
