A mobile ad hoc network (MANETs) is a self-organizing network that consists of mobile nodes that are connected through wireless media. A number of unique features, such as lack of infrastructural or central administrative supports, dynamic network topologies, open communication channels, and limited device capabilities and bandwidths, have made secure, reliable and efficient routing operations in MANET a challenging task. The ultimate goal of the security solutions for MANET is to provide

The primary focus of this work is to provide transport layer security for authentication, securing end-to-end communications through data encryption. It also handles delay and packet loss. The MANET transport layer protocols provide end-toend connection, reliable packet delivery, flow control and congestion control. The proposed model combines Zone Routing Protocol(ZRP) with Wireless Transport Layer Security(WTLS) provides authentication, privacy and integrity of packets in both routing and transport layers of MANET and also to defend against Denial of Service(DoS) attack.ZRP with WTLS is found to be a good security solution even with its known security problems. The simulation is done using network simulator qualnet 5.0 for different number of mobile nodes. The proposed model has shown improved results in terms of Average throughput, Average end to end delay, Average packet delivery ratio and Average jitter.
