In this paper we present a brokerage system for using idle computing resources as a micro-currency for Web services hardly quantifyable with real currencies as downloading stock charts or accessing a search engine. The Locust (LOw cost Computing Utilizing Skimmed idle Time) system acts as a Broker for micro-payable services by demanding a part of the user’s idle computing resources in exchange ...

The following are some bugs and issues, which were found in IEEE 802.11 implementation in ns-2.30. Infrastructure mode : Infrastructure mode support is very weak in ns2. Scanning, Association and Authentication functions have not been implemented. Beacon frames are also absent in the current implementation. While a beacon patch was developed last year by Matteo Rossi, which provided beacon fram...

Shortest path computation is required by a large number of applications such as VLSI, transportation and communication networks. These applications, which are often very complex and have sparse networks, generally use parallel labeling shortest path algorithms. Such algorithms, when implemented on a distributed memory machine, require termination detection methods; these methods consist of some...

This paper analyzes an M/M/2 queueing system with two heterogeneous servers. Both servers goes on vacation when there is no customers waiting for service after this server 1 is always available but the other goes on vacation whenever server 2 is idle. The vacationing server however, returns to serve at a low rate as an arrival finds the other server busy. The system is analyzed in the steady st...
