Mobile Ad-hoc NETwork (MANET) is a decentralized wireless network. Here the mobile nodes make and break the links with the neighboring nodes available in the radio range without actually being physically connected. These networks are temporary and keep on changing from time to time. MANET applications are getting importance in both civilian and military areas. MANETs can be applied in disaster communications and used as the backup network of traditional mobile communication networks as well. Network throughput, number of packets dropped and average latency are important parameters to evaluate the performance of wireless ad hoc network.
