Handling Disconnections in LTE Network-based Mobile Grid

LTE (Long-Term Evolution Network) is gaining momentum with its success in smart grids. Many time-critical applications can be hosted in mobile grids using LTE. High degrees of intermittent connectivity and disconnections are prevalent in a mobile grid. When a mobile node disconnects, the processes become orphans and require migration. This paper proposes a non-DHT based heap overlay to determine a destination host for the migrated process to continue computing with minimum disruption. The overlay facilitates structured communication in search of a destination node. Simulation results indicate that the proposed approach has constant time complexity than random or learning-based techniques. It is also found to have reduced maintenance overheads. Further, a dedicated bandwidth allocation is proposed for exporting the process state from source to destination identified.
