In this paper a detailed analysis of Data Encryption Standard (DES), Triple DES (3DES) and Advanced Encryption Standard (AES) symmetric encryption algorithms in MANET was done using the NetworkSimulator 2 (NS-2) in terms of energy consumption, data transfer time, End-to-End delay time and throughput with varying data sizes.Two simulation models were adopted: the first simulates the network performance assuming the availability of the common key, and the second simulates the network performance including the use of the Diffie-Hellman Key Exchange (DHKE) protocol in the key management phase.The obtained simulation results showed the superiority of AES over DES by 65%, 70% and 83% in term of the energy consumption, data transfer time, and network throughput respectively.On the other hand, the results showed that AES is better than 3DES by approximately 90% for all of the performance metrics.Based on these results the AES was the recommended encryption scheme.
