In order to effectively manage the communication nodes in Mobile Ad Hoc Network (MANET), it is important to know the topology of such networks. Traditional Ad-hoc On-demand Distance Vector (AODV) protocol can not get the MANET topology due to the lack of the topology discovery mechanism. Aiming at this problem, an enhanced topology discovery algorithm based on AODV (AODV-TD) is proposed. AODV-TD can not only obtain the topology of dynamic network by topology discovery request, but also realize route discovery among nodes. Finally, the proposed algorithm is implemented on a hardware platform using CC1100, and the experiment results show that, even the network changes dynamically, AODV-TD can still discover the network topology rapidly and accurately, so that contribute to reducing the route discovery time and the RREQ forwarding packets.

Introduction: The aim of the securing energy routing protocol, is to provide the countermeasures to the attacks par-ticularly to the black hole in mobile ad-hoc network, and enhancing the network performance metric throughput al-so reducing the end-to-end delay between the nodes in the network.To build the protocol that enhances the perfor-mance of the network by modifying the existing DSR protocol by introducing new route discovery mechanism in the proposed protocol. Method: The proposed protocol implementation has two phases, route request/reply phase and route confirm phas-es. During the route discovery process, the route discovery from the source to destination process are described by sending the RREQ packet from the source hub as shown in Fig. 1(a), when it does not have one accessible and crav-ings a route to a destination. The source node transmits the RREQ to its associate nodes and the destination node re-ply with RREP. When the source receives reply message, the source node respond with reverse path with a confirm RCON message and providing security to the nodes in the network. Results: To verify the performance of the proposed protocol against the existing DSR protocol are compared with respect to various network metrics like end-to-end delay and packet delivery ratio and validated the result by com-paring both routing algorithm using Network Simulator 2. Conclusion: The results of the proposed SERP strongly safeguard against the attacks in the network and the packet delivery ratio is increased compared with the DSR also the end-to-end delay is reduced in the proposed protocol. Discussion: Mobile ad-hoc networks are being dynamic in nature, it associates with issues relating to secure routing, energy and are generally vulnerable to several types of attacks. The DSR is one of the widely used reactive proto-cols available for the mobile ad-hoc network and the proposed work enhancing the security of the network in the existing pro
