A Model for Coordinating Jobs on Mobile Wireless Computational Grids

Abstract

This paper presents a report of a study carried out to develop a job coordination model for the active resources on a mobile wireless computational grid. This was with a view to addressing the problem of frequent disruptions in connections and high computation time for a job resulting from the mobility of the mobile resources actively processing tasks. The proposed framework is a load-balancing three tier hierarchical system configuration and scheduling policies employing mobile Agents coordinating messengers carrying data and instructions among the hierarchical structured nodes. The model achieves a remarkable performance as compared with theoretical values in that there were reduction in response times and latencies when simulated with various workloads. The proposed migration and checkpointing approach ensures that currently executing processes are not always migrated because of loss of signal only, but only with reduction in battery power of the mobile hosts within the allocated time for processing a task.

“…En este caso, al menos dos escenarios pueden ser posibles: i) reasignación de tareas cuando los recursos fallan o están próximos a fallar y ii) reasignación de tareas para equilibrar la carga de los diferentes nodos y así maximizar la cantidad de tareas que se pueden completar. Ejemplos de estrategias reactivas pueden encontrarse en [35] y [36].…”
