same proposed FF-AOMDV protocolis used along with the bandwidth as a fitness value.

Now the calculations forselecting routes towards the destination will be according to energy, distanceand also bandwidth. The same performance metrics used in the experiments: 1. Packet Delivery Ratio.2. Throughput.

3. End-to-end delay.4. Energy Consumption.5. Network Lifetime.are used here to evaluate theresults.

Thus the proposed work is expected to improve the performance ofmobile ad hoc networks by prolonging the lifetime of the network. Theperformance will be evaluated in terms of throughput, packet delivery ratio,end-to-end delay, energy consumption and then compare with the results ofexisting AOMDV protocol. Available Bandwidth:            Bandwidth is also known as the datatransfer rate. It describes the data sent out by means of connection over aspecified time and the bandwidth is expressed in bps. Bandwidth is the bit-rateof the existing or the consumed information capacity uttered normally in metricmultiples of bits per second. As the bandwidth is kept high the energyconsumption is also high. The data packets send increases and the energyconsumed at each node is also high.

The transmission power consumption is highbecause the packets send are more. When the bandwidth is taken as a parameteralong with the distance and energy, energy consumption varies as:1. when distance increases energyconsumption also increases and when the route distance is less energy consumedwill be low.2. when bandwidth is high energyconsumption  is also high  and when it is  less energy consumed will be low. Thusbandwidth is the parameter considered here and the simulation has scenarios likenode speed, packet size and simulation time.

simulations are done by keeping thescenarios as: varying the packetsize(64,128,256,512,1024) and keep both thenode speed and simulation time fixed. Packet delivery ratio, Throughput,End-to-end delay, Routing overhead ratio are  the performance metrics used to test the scenarios. In the proposedsystem as the bandwidth is the other parameter the mathematical model is to befind based on the three parameters energy, distance and bandwidth.

 5. CONCLUSION:Energy ef?ciency (EE) is anessential aspect of mobile ad hoc networks (MANETs).secured routing protocol isproposed which is energy efficient and security is provided for both link andmessage without relying on the third party. A secure communication among theparticipating nodes is offered by the environment of MANETS. Energy consumptionplays an important role in network lifetime. Since network mobility is animportant factor and network’s energy is consumed in data communication,Cross-Layer design approach is used to enhance the transmission power for powercontrol. Energy consumption can be reduced by the prevention of securityattacks on routing protocols.

Here to find the optimal path in multipathrouting, distance and energy are the fitness values used. It is proposed to usethe network resource bandwidth and calculations in selecting the routes towardsthe destination will be according to the distance, energy and also bandwidth.Thus the proposed work minimizes energy consumption and maximizes networklifetime. REFERENCES:1.
