Authenticated Key Exchange (AKE) protocols represent an important cryptographic mechanism that enables several parties to communicate securely over an open network. Elashry, Mu and Susilo proposed in 2015 an Identity Based Authenticated Key Exchange (IBAKE) protocol where different parties establish secure communication by means of their public identities. The authors also introduced a new secu...

Widespread use of networked multimedia applications emphasizes the need for robust communication protocols that can provide fault tolerance and error resiliency. Multiple-description (MD) coding is a technique used to mitigate channel failure when retransmission is expensive or impossible. Multiple descriptions lattice vector quantization has become a popular choice for robust data transmission...

Non-blocking atomic commitment protocols enable a decision (commit or abort) to be reached at every correct participant, despite the failure of others. The cost for non-blocking implies however (1) a high number of messages and communication steps required to reach commit, and (2) a complicated termination protocol needed in the case of failure suspicions. In this paper, we present a non-blocki...

In wireless sensor network (WSN), preditibution of cryptographic keys is possibly the most practical approach to perfect network communications. In this paper, we propose a new secret key predistribution scheme to achieve a higher connectivity in WSN. For this we combine a random key predistribution scheme and hash chain method based on the prior knowledge of sensor node deployment. The propose...

in a military organization, the role of transportation should be much more strong and strategic character for the organization. in this context, the evaluation of operating ability of transportation and eliminate defects and problems, can help the managers to improve performance and increase the effectiveness and efficiency of transportation in the assigned missions. in this study, a model is p...

One abstract method for the study of network transportation is proposed in this paper. By interpolating the properties of the edges that constitute network into the two leading parameters of the nodes, this method can abstract the configuration of real-life transportation networks without losing the influence of the distance and the capability of the physical facilities, which are essential par...

This paper presents an agent-based approach to design a Transportation Regulation Support System (TRSS). Based on a multi-agent modeling of a urban transportation network, the objective of our approach is to integrate the functionalities of the existing information system with the functionalities of a decision support system. The TRSS monitors the network activity and adjusts itself to the envi...

Because middleware abstractions remove the need for lowlevel network programming, modern distributed component systems expose network volatility (i.e., frequent but intermittent outages) as application-level exceptions, requiring custom manual handling. Unfortunately, handling network volatility effectively is nontrivial—the programmer must consider not only the specifics of the application, bu...

It is difficult to determine whether specific weather events like the storms in Washington can be definitively attributed to climate change or if they are severe storm occurrences within otherwise natural weather patterns. However, consensus in the scientific community indicates that major storms and other events including inundation of coastal roads from a rising sea level, erosion of roadways...
