This paper investigates the resource allocation problem in heterogeneous cognitive radio networks (HCRNs). In this paper, two types of users, i.e., multi-homing and single-network cognitive radio users (CRUs), are considered to coexist in HCRNs. Multi-homing CRUs can access multiple networks simultaneously, while single-network CRUs can be served by only one network at a time. With the aim of maximizing...
Partial disjoint multipath routing has been largely deployed in networks such as wireless sensor networks, outperforming single path routing in load balance and fault tolerance, etc. However, disjoint multipath routing has not been widely deployed in networks, because the difficulty of designing an accordingly distributed algorithm. Software defined networking (SDN) is based on the abstract of the...
Extraction of relevant features is of significant importance for brain tumor segmentation systems. To improve brain tumor segmentation accuracy, the authors present an improved feature extraction component that takes advantage of the correlation between intracranial structure deformation and the compression resulting from brain tumor growth. Using 3D nonrigid registration and deformation modeling...
