research on load balancing mechanism based on handoff in heterogeneous network platform
Modern service industry is a new kind of service industry based on information & communication technologies and modern management thinking, which is in accord with the concept "Service Science" by IBM. A heterogeneous network platform is founded to implement the applications of modern service industry. In this paper, an intelligent handoff algorithm is proposed to keep the service continuity in the heterogeneous network platform. And service class differentiation is considered to define the service priority according to service characters of real-time traffics and non-real-time traffics. A load balancing mechanism based handoff is proposed to balance the load of a network or cell by comparing the current load value with corresponding throughput thresholds. Simulations illustrate that the load balancing algorithm can improve the blocking probability, call dropping probability and resource utilization to an extent.
