Una mejora del framework SNMP de equilibrio de carga para controlar los computadores de la WLAN en zonas de cobertura reducida

Abstract

A network formed by desktop and portable computers is a useful environment for doing parallel computing. In this infrastructure we implement Master/Slave parallel distributed programs which exhibit strict data dependences among iterations and parallel calculations inside an iteration. Due to the dynamic behaviour of portable computers is necessary to keep in mind that they can move out of coverage area at any time. In a previous work, we developed a load balancing software framework based on Simple Network Management Protocol (SNMP) that considers the beacon strength in the portable computers for executing this kind of applications efficiently. However, when a portable computer is located in a limited coverage area, our framework considers that this resource is unavailable, and therefore it can’t be used. For that reason, in this paper we present a mechanism that improves the performance of our framework SNMP, allowing us to use the portable computers while there is a wireless link.
