Underwater wireless acoustic communication is a central aiding skill used in underwater monitoring with the help of sensor nodes. Designing Underwater wireless networking is challenging as the water environment is dynamic as well as hard. In this paper we combine OFDM MIMO with IDMA to improve the network performance. The experimentation was simulated using Aqua Sim simulator an underwater imitation software that is based on NS2. The key objective of our paper is twofold. First is connection of communication functionalities such as BPSK modulation, Turbo code, Random Interleaver, UWMAC and three routing protocols. This implementation has modulation scheme, MAC and routing protocol from Aqua Sim simulator. Where the novel contribution to the work is implementation of Turbo code in NS2 for the appealing results. Secondly the OFDM MIMO and IDMA OFDM MIMO implementation is tested with 50 nodes and the various parameters such as BER, Throughput, delay, packet delivery ratio, energy consumption has been investigated. IDMA OFDM MIMO gives good results in terms of BER, packet delivery ratio, Throughput but consumes more energy.
