Description
High Level Architecture (HLA) is architecture for
reuse and interoperation of simulations. In HLA paradigm, the
Runtime Infrastructure (RTI) provides a set of services. Data
Distribution Management (DDM) service reduces message traffic
over the network. DDM aims to control and limit the data exchanged
between federates during federation. Each federate may inform the
RTI about its intention to publish some data or it may subscribe to
receive a subset of the published data. DDM services are used to
reduce the transmission and receiving of irrelevant data and aimed at
reducing the communication over the network. These services rely on
the computation of the intersection between “update” and
“subscription” regions. When calculating the intersection between
update regions and subscription regions, the higher computation
overhead can occur. Currently, there are several main DDM filtering
algorithms. This paper proposes the layer partition-based matching
algorithm for DDM in the HLA-based large-scale distributed
simulations. The new algorithm chooses the dynamic pivot based on
regions distribution in the routing space. The binary partition-based
algorithm is fundamentally based on a divide and conquers approach.
This algorithm always chooses the midpoint as the pivot point of
routing space. This approach promises low computational overhead,
since it does not require unnecessary comparisons within regions in
different partitions. The proposed algorithm firstly calculates the
regions distribution. Then, the partitioning among regions performs
based on the result of choosing pivot based on region detection and
defines the matching area that entirely covers all regions which need
to match with regions at pivot point. The proposed algorithm
provides the more definite matching area between update region and
subscription region during matching process. This algorithm
guarantees low computational overheads for matching process based
on the overlapping degree between the regions and reduce the
irrelevant message among federates.
