Energy efficient and Demand based Topology Maintenance for various network traffic conditions
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2012, Vol 1, Issue 4
Abstract
Due to the nodes’ limited resource in the adhoc networks, the scalability is the crucial for network operation. 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. The first method is not effective in high traffic conditions. Similarly, the second method is not effective in low traffic networks. So, in this paper we propose a Demand Based Topology (DBT) to reduce the energy consumption for mobile ad hoc network, by dynamically adjusting the topology for various network traffic conditions. We have simulated our proposed protocol DBT by using AODV [8] as routing protocol in network simulator ns2.33 [1] and compared with AODV and SPAN [3]. The simulation studies revealed that the proposed scheme perform better in terms of energy, delay, and delivery ratio.
