Wireless sensor networks (WSNs) have been applied in networking devices, and a new problem has emerged called source-location privacy (SLP) critical security systems. In wireless networks, hiding the location of source node from hackers is known as SLP. The WSNs limited battery capacity low computational ability. Many state-of-the-art protocols proposed to address SLP problems other such power....

The paper studies distributed cooperative multi-agent exploration methods in settings where the overall benefit of an opportunity is the minimum of individual findings and the exploration is costly. The primary motivation for the model is the multi-channel cooperative sensing problem which draws from the inter-vehicular cognitive offload paradigm. Here, vehicles try to coordinate an offload cha...

This paper presents an activity-based cost model for printed wiring board (PWB) fabrication in which the process steps are defined by material processing activities. The model is designed to be used during system planning and tradeoff analysis prior to physical design. In many activity-based manufacturing cost models, activities are based on equipment and facilities (“equipment-centric”). In th...

For à trous wavelet-based remote sensing image fusion, it is significant to determine the number of decomposition levels (NDL) to derive the best tradeoff between the spatial and spectral qualities of the fused image. The tradeoff is modeled as a cost function from a novel three-dimensional variational point of view. By solving this cost function, a new fusion scheme is proposed that can be use...

Caching is an effective mechanism for reducing bandwidth usage and alleviating server load. However, the use of caching entails a compromise between content freshness and refresh cost. An excessive refresh allows a high degree of content freshness at a greater cost of system resource. Conversely, a deficient refresh inhibits content freshness but saves the cost of resource usages. To address th...

Deep learning technology has made great progress in multi-view 3D reconstruction tasks. At present, the mainstream solutions adopt different ways to fusion features from several views. Among them, attention-based aggregation function performs relatively well and stably, however, it still an obvious shortcoming strong independence of each view during predicting weights for merging leads a lack a...

In secure multicast communication, group key management plays an essential role for the guarantee of data confidentiality and integrity. Because communication bandwidth is a limited resource, most group key management schemes for scalable secure multicast communications have focused on reducing the number of update messages, i.e., communication cost. To alleviate the scalability problem, a key ...

Functional criteria often drive the component selection in the assembly of a software system. Minimal distance strategies are frequently adopted to select the components that require minimal adaptation effort. This type of approach hides to developers the non-functional characteristics of components, although they may play a crucial role to meet the system specifications. In this paper we intro...

Network Function Virtualization (NFV) allows datacenters to consolidate network appliance functions onto commodity servers and devices. Currently telecommunication carriers are re-architecting their central offices as NFV datacenters that, along with Software-Defined Networking (SDN), help network service providers to speed deployment and reduce cost. However, it is still unclear how a carrier ...

Managers often face difficulties when making project decisions that involve large number of interrelated activities – the planning and scheduling of which is project management. Most problems often arise in areas such as product development, production planning and control and setting up the production facilities. One important aspect of project management is activity crashing, i.e. reducing th...
