EXTENDS LIFE TO THE MOBILE AD-HOC NETWORK BY DETECTING MALICIOUS NODES AND REDUCING ENERGY CONSUMPTION USING ROUTING PROTOCOL

The incidence of malicious nodes in an ad-hoc network worsens the performance of the network. A novel approach to detect increasing intrusion of malicious nodes is proposed to protect against attack on MANET vector route protocol. These malicious nodes can reduce overall data access in the network, with the increase in query delays. However some nodes can only decide to support partially or not at all with other nodes. Those mobile nodes that take their own packets but do not send neighbors to packets are known as the unfaithfully nodes. This type of malicious nodes can reduce overall data access in the network. Due to this kind of problem, the overall process of MANET was affected. The proposed approach employs a technique for determining the conditions less than which the first stage is based on the secure malicious nodes detecting method (SMND) to the network and the second step is based on the smallest route to reducing energy consumption using AODV (REC-AODV). In accumulation to identifying malicious nodes, it have been experiential that in this approach, ad- hoc routing has less security and less communication breaks. MANET has many issues that attract researchers to work in these areas. Experimental outcome show that the proposed methodology is to successfully detect malicious nodes, and with the help of routing protocol, the shortest route reduces the energy consumption of the packets in the network, which will be for long life in the network. By keeping these parameters in mind we calculate the packet delivery ratio, throughput, energy usage, congestion control and routing overhead
