Abstract : The Multimedia based application services have been getting attention in recent years in various fields. These services require a stringent delay resistant protocol in order to provide the best Quality of Service to end users. Existing protocols are predominantly designed using load balancing, tree, multi-tree and mesh based mechanisms. These mechanisms suffer in the presence of channel noise and incur more delay due to improper multicasting techniques adopted. Overlay network using hybrid (tree over mesh) structure along with multicasting strategies are used to address this issue. In this paper, an Improved Delay Resistant Adaptive Multicasting (IDRAM) model which adopts hybrid overlay creation, sub-packet based multi path transmission technique and error correction based on Forward Error Correction along with arbitrary IDRAM-A and selective IDRAM-S multicasting techniques are proposed and evaluated. Simulation is conducted to calculate frame success ratio, throughput, number of packet retransmission and transmission delay. The results obtained prove that IDRAM-S outperforms better than IDRAM-A and existing sub packet based multi path techniques. The number of retransmission requests made by IDRAM-S is reduced compared to the existing model. This reduction in the number of retransmission enables in minimizing end to end delay and thereby achieve stringent delay constraints associated with multimedia data delivery.
