Grid Nodes

Computation in the mobile grid nodes under the cellular network environment requires an efficient management of wireless channels along with the user mobility. Due to random movement of the mobile devices, the load over the cells in terms of initiation of new computation or carryover computation (handoff) may vary dynamically. This may result in non-availability of free channels for Inter-task communication leading in the drop of carryover computation or to initiate the new computation in the current cell. The proposed work designs a model by instigating substantive cooperation among underutilized and the overloaded cells, considering importance to the frequency reuse and assigning priority to the on-going computation in the computational mobile grid. The model seeks cooperation by grouping the cells in different sizes to reduce the blocking and dropping of the computation. Blocking of the communication is very serious in computational mobile grid environment as the drop may result in the termination of the computation. The model aims at minimizing the Call Block Probability (CBP) and Call Drop Probability (CDP) in the mobile grid by making the clusters of different sizes. A simulation experiment to evaluate the performance of the proposed model reveals the effectiveness of this model.

Successful Execution

In mobile grid environment, the existing fault tolerance techniques are not feasible and proficient. The present techniques lack to achieve the maximum profit associated with successful execution of the tasks and is deemed to be costly. Hence, we propose a fault tolerance mechanism for scheduling in mobile grid environment. In this technique, we consider failures that occurs during the execution of computing-focused and communication-focused jobs. In order to detect the failure, a novel structured data packet is sent to the destination. The destination acknowledges with a specific type of data packet corresponding to the received packet. The sender analyses the acknowledgement data packet identifies the place and nature of error. Finally, a fault recovery action is performed using the FTMS technique. By simulation results, we show that the proposed technique is reliable and efficient.
