As wireless and 3G networks become more crowded, users with mobile devices have difficulties in accessing the network. Opportunistic networks, created between mobile phones using local peer-topeer connections, have the potential to solve such problems by dispersing some of the traffic to neighboring smartphones. Recently various opportunistic routing or dissemination algorithms were proposed an...

In this article, we study how predator behavior influences the aggregation of prey into herds. Game-theoretic models of herd formation are developed based on different survival probabilities of solitary prey and prey that join the herd and on the predator's preference of what type of prey to search for. For an intentional predator that will only pursue its preferred type of prey, a single herd ...

Networked organizations, consisting of enterprises who exchange things of economic value with each other, often have participants who commit a fraud or perform other actions, not agreed in a contract. To explore such opportunistic behavior, and to design solutions to mitigate it, we propose the econtrol approach. This approach takes the valuable objects, which are exchanged between enterprises,...

This paper presents an extension of the Motivated Learning model that includes environment masking, and opportunistic behavior of the motivated learning agent. Environment masking improves an agent’s ability to learn by helping to filter out distractions, and the addition of a more complex environment increases the simulation’s realism. If conditions call for it opportunistic behavior allows an...

Police patrols are used ubiquitously to deter crimes in urban areas. A distinctive feature of urban crimes is that criminals react opportunistically to patrol officers’ assignments. Compared to strategic attackers (such as terrorists) with a well-laid out plan, opportunistic criminals are less strategic in planning attacks and more flexible in executing them. I proposed two approaches to genera...

Opportunism a behavior can be found in any relational exchange in many forms. In this respect, opportunistic behavior has been recognized one of the historical factors that have tremendous effects on the relationship development between buyer and seller. A conceptual framework of the research’s main variables is presented, the antecedents which are dependence, formalization, relational norms an...

This paper explores how uncertainty reduction due to increased forecasting accuracy, which is one of main benefits associated with the adoption of Business Intelligence (BI) systems, will affect the behavior of knowledge workers and how this change in their behavior will impact the appropriation of benefits from BI investments. The study uses a micro-economic model in order to show that higher ...
