Energy Efficient Topology Based on Demand for MANETS Using Directional Antenna
M. Tech-VLSI · 2014
Energy efficient topology in Ad-hoc networks can be achieved mainly in two different ways. In the first method, network maintains a small number of nodes to form a connected backbone and the remaining nodes sleep to conserve energy. This method is effective for low traffic networks. Energy efficiency in the second method is achieved by power control technique. This technique is effective in high traffic conditions. In order to reduce the energy consumption for mobile ad hoc network the topology is dynamically adjusted for various network traffic conditions. The simulation of DBET protocol will be carried out using Ad hoc On-demand Distance Vector (AODV) as a routing protocol in a network simulator. We have simulated protocol DBET by using AODV (1) as routing protocol in network simulator ns2.33 (2) and compared with AODV and energy consumption while using omnidirectional and directional antennas is also compared. The simulation studies revealed that the proposed scheme perform better in terms of energy, delay and delivery ratio and using directional antenna energy consumption is further reduced.
