Many routing protocols have been designed for Ad Hoc networks. However, most of these kinds of protocols are not able to react fast enough to maintain routing. This paper presents a Proposed Routing Protocol (PRP) that repairs the broken route by using information provided by nodes overhearing the main route communication. When links go down, our protocol intelligently replaces these failed lin...

To deliver messages in the VANET (Vehicular Ad hoc Network) environment, vehicles are connected by wireless communications. The communications among vehicles is not stable by the vehicle speeds or the surrounding environments of roads. It is required to maintain stable communications between vehicles. In this paper, we modify the WAVE (Wireless Access in Vehicular Environments) communication st...

The authors examined whether the negative behavior of 1 Black male would influence White participants' perceptions of Black Americans and behavior toward another Black person. In Study 1, it was found that participants in the Black-negative condition tended to stereotype Blacks more than participants in the Black-control condition did. It was also found that participants who had observed a nega...

Reliable broadcast is an important primitive in wireless mesh networks (WMNs) for applications such as software upgrade, video downloading, etc. However, due to the lossy nature of wireless link, it is not trivial to achieve the reliability and efficiency at the same time. In this paper, we put forward R-Code, a reliable and efficient broadcast protocol based on intra-flow network coding. The k...

Software agents must have some degree of autonomy in order to be able to adjust to changing and sometimes unpredictable situations due to communication problems. Introducing so-called overhearers for monitoring team activities and helping recovery from failures seems to be a very promising approach. In this paper, we claim that having a “global” representation of the interaction protocol can be...

The Internet of Things (IoT) is currently used in many wireless sensor network (WSN) applications. Conventionally, the WSN’s energy consumption considered as one prime concerns. mostly due to sensing, data processing, communications and other wasted energies such idle listening, collisions overhearing. These nodes are regularly powered by an external power source consequently have a shorter lif...

Underwater acoustic sensor networks (UASNs) have attracted great attention in recent years and utilizes as a part of oceanic applications. This network has to deal with propagation delay, energy constraints limited bandwidth which are strenuous for designing Medium Access Control (MAC) protocol underwater communication. There also exists an idle channel listening overhearing problem sets down t...

Not only the proliferation of 802.11, but also the capability to determine the position of mobile devices make 802.11 highly appealing for many application areas. Typically, a mobile device that wants to know its position regularly performs active or passive scans to obtain the signal strength measurements of neighboring access points. Active and passive scanning are survey techniques originall...

Artificial agents, as well as humans, not only interact with individual peers but often need to communicate with groups. Indeed, group communication is frequently required in agent conversation protocols. In this work, we provide a formal semantics of group communication that allows reasoning on the intended recipients of an utterance as well as third parties that may be, voluntarily or not, li...
