Operators Intervention Strategies with New MCDM for Load Balancing in Heterogeneous Mobile Networks

Wireless networks are designed to operate independently. With the many existing inconveniences of 3G networks, operators are persuaded to switch to heterogeneous access networks. This will mainly reduce the costs that operators should pay in order to move to 4G; and thus make use of the existing networks infrastructures, to come up with heterogeneous environment where multiple wireless technologies coexist. In this paper, three strategies along with the operators’ intervention are programmed: binary, binary with return to initial condition, and fuzzy. The reason behind this is to select the best strategy (least drop probability, least delay, best performance parameters, etc), which is the fuzzy one; whereby regular filling of the different networks is provided, and thus network fluctuation is well illustrated. As for the worst strategy, it is the binary with return to initial condition; whereby operators will have less resources to exploit, and so less throughput and higher delay.
