Abstract

Many ITS applications are designed based upon centralized vehicle-to-center communication scheme. The backend systems deal with the requests from the front-end devices (FED) and respond to the request information for completing applications scenarios. However, huge amount of FEDs may generate mass client requests and result in communication server bottleneck problem (CSBP). In this paper, an adaptive hierarchical load balance approach with the concepts of divide and conquer, dynamic load distribution and balancing for resolving the CSBP is proposed. A work load factor is defined for balancing the loads of communication servers to maintain the quality of service, and a fail-over procedure is automatically triggered to assign a new responsible communication server when a communication server fails. By applying the proposed method, client requests can be almost averagely distributed to the available communication servers, which reduces the probabilities of regional congestion and enhance the overall service quality.
