To provide effective communication in the wireless mesh network (WMN), several algorithms have been proposed. Since the possibilities of numerous failures always exist during communication, resiliency has been proven to be an important aspect for WMN to recover from these failures. In general, resiliency is the diligence of the reliability and availability in network. Several types of resilienc...

Information resiliency refers to the continuous availability of uncorrupted mission-critical information to support business or military operations, even under the threat of a cyber attack. An information resilient enterprise will continue to engage in its critical operations, despite the attacker’s attempts to intrude, corrupt or deny service. The manner and efficiency with which the operation...

in this paper, we develop a freight transportation model for railway network considering hazmat transportation issue. in the transportation system considered, different customers can request for carrying hazmat and non- hazmat boxes. it is assumed that the sequence of the trains in the network is known. the objective is assigning the non-hazmat boxes and hazmat boxes to wagons of the trains so ...

nowadays, the environmental impact of transportation project and, especially air pollution impacts, are major concerns in evaluating transportation projects. based on this concern, beside definition of traditional objective functions like total travel time and total investment cost, different type of environmental related function is considered as objective function in urban network design. in...

Since the devastating attacks of September 11, 2001 there have been numerous discussions on the issue of terrorism and terrorist networks, such as al Qaeda, within the media and the intelligence community. At times these discussions have created an image of the terrorist phenomenon as one of a monolithic and unstoppable menace continuing to spread around the world unabated. Lost in these discus...

This paper presents a general methodology to calculate the resiliency of complex engineered systems based on complex network theory. Graph spectral theory has been used simultaneously with complex network theory for years. Resiliency is a key driver in how systems are developed to operate in an expected operating environment, and how systems change and respond to the environments in which they ...

Sustainable supply chain management is a topical area which is continuing to grow and evolve. Within supply chains, downstream distribution from producers to customers plays a significant role in the environmental performance of production supply chains. With consumer consciousness growing in the area of sustainable food supply, food distribution needs to embrace and adapt to improve its enviro...

Real-time transmission of video data in network environments, such as wireless and Internet, is a challenging task, as it requires high compression efficiency and network friendly design. H.264/AVC is the newest international video coding standard, jointly developed by groups from ISO/IEC and ITU-T, which aims at achieving improved compression performance and a network-friendly video representa...
