摘要：An ad hoc network is an indivisible part of the networks. It is an infrastructureless network. Whenever node wants to communicate with neighborhood node, it does not depend on the centralized infrastructure. Ad hoc is dynamic in nature. Due to the open structure, node can be easily impersonated by the several attacks like Denial of Service (DoS) attack, Wormhole attack, black hole attack and Packet forwarding attack etc. In the presence of the attack, the energy consumption of the network can be increased unlimitedly. In this research work, we have considered three factors like node mobility, malicious behavior and unauthenticated node, in order to minimize the energy consumption of the node. By limiting these factors, the node consumes less energy. For that, we have developed the Energy Based Routing Algorithm (EBRA) which is integrated into the Dynamic Source Routing (DSR) protocol to ensure the minimum energy consumption rate. The proposed scheme consists of three phases. In first phase, nodes energy consumption is limited with the high mobility. In second phase, the effect of malicious behavior is reduced to avoid the replaying of packets. In third phase, the unauthenticated node is identified using the digital signature verification. By simulation results the proposed scheme achieves less energy consumption rate, more energy efficiency, better throughput, less overhead and delay in the presence of the malicious nodes than the existing schemes.
