Abstract—In this article we introduce the concept and the first implementation of a lightweight client-server-framework as middleware for distributed computing. On the client side an installation without administrative rights or privileged ports can turn any computer into a worker node. Only a Java runtime environment and the JAR files comprising the workflow client are needed. To connect all c...

Nowadays, Wireless LANs (WLANs) have been densely deployed to provide the last mile delivery of Internet access to mobile clients. As the population of WLAN clients who carry WiFi-enabled devices keeps increasing, WLANs are often crowded and WLAN clients may thus encounter serious performance degradation due to channel contention and interference. Therefore, in this paper we present a new packe...

Wireless mesh networks (WMNs) consist of mesh routers and mesh clients, where mesh routers have minimal mobility and form the backbone of WMNs. They provide network access for both mesh and conventional clients. The integration of WMNs with other networks such as the Internet, cellular, IEEE 802.11, IEEE 802.15, IEEE 802.16, sensor networks, etc., can be accomplished through the gateway and bri...

This paper provides a theory of endogenous leverage through rehypothecation in collateralized intermediation. Overcollateralization with an rehypothecation option arises as an optimal contract form between broker dealers and their clients to mitigate adverse selection on collateral quality. Such contract prevents the broker dealers from taking advantage of private information on collateral qual...
