LDMA 的修改版本被提出为 ELDMA（使用分散式移动代理的增强负载平衡决策），它通过通信介质在网状拓扑中组织的 Web 服务器之间平均分配负载。在 LDMA 中，当 Web 服务器进入集群时，就会为其分配排名。排名显示了集群中服务器处理请求的优先级。每个服务器通过交换消息来参与处理请求的决策。它会导致服务器之间的通信开销较高。在所提出的方案中，根据 CPU 处理时间和内存利用率动态地将排名分配给服务器。除此之外，通过限制服务器之间的消息交换来减少通信开销。使用负载分布、吞吐量和网络流量来评估所提出方案的性能。
A modified version of LDMA is proposed as an ELDMA (Enhanced Load balancing Decision making using Decentralized Mobile Agent), which distributes the load equally among the Web servers organized in a mesh topology, by a communication media. In LDMA, the rank is assigned to the Web server as and when it enters the cluster. The rank shows the priority of processing a request by the servers in the cluster. Each server involves in the decision making for processing the request by exchanging the message. It causes high communication overhead between the servers. In the proposed scheme, a rank is dynamically assigned to the servers based on CPU processing time and memory utilization. In addition to that the communication overhead is reduced by restricting the message exchange between the servers. The performance of the proposed scheme is evaluated using load distribution, throughput and network traffic.
