摘要：MANET is a dynamically varying network of wireless nodes that may move randomly independent of each other. Security, a serious crisis in MANET has innovative challenges such as data confidentiality and integrity. Malicious nodes or data hackers make packet dropping or interference in the routing messages in the network. To overcome these problems this paper proposes a secure optimized routing system with data confidentiality. Multipath route is optimized by selecting the best path using PSO (Particle Swarm Optimization) algorithm. Malicious nodes are identified by selecting the monitoring nodes derived from the network parameters: throughput bandwidth, and energy. Key management scheme with MD5 hash encryption is proposed to improve the secure data communication. The intent of MD5 algorithm is to generate the hash value for transmitting the data securely through the optimized route path. By simulation results, we show that the proficient of the proposed technique in terms of data confidentiality.
