In this paper, a hierarchical load balancing technique has been presented, which is based on variable threshold value. Through this paper, an attempt has been made to solve the problem of load balancing while maintaining the resource utilization and response time with the help of sender initiative policy. The proposed technique is suitable for dynamic and decentralized Grid environments. The load is divided into different categories like lightly loaded, under-lightly loaded, overloaded, normally loaded, based thresholds values. A threshold value, which can be found out using load deviation, is responsible for transfer the task and flow of workload information. In order to increase the response time and decrease throughput of the Grid, a sender initiated policy has been introduced to reduce the communication overhead. The model has been rigorously examined over the GridSim simulator using various parameters like execution time, response time, makespan etc. Experimental results prove the superiority over existing techniques.
