TAILIEUCHUNG - Energy efficient multicast through acknowledgment based TPC in adhoc wireless networks

The proposed analytical model successfully captures the key characteristic of a reliable power saving system: the data delivery procedure starts periodically at the previously negotiated time, but ends at a rather random time with its distribution depending on the end time of data delivery in the last delivery period as well as the arrival rate of incoming traffic. | ISSN:2249-5789 Sangavi S et al, International Journal of Computer Science & Communication Networks,Vol 2(2), 194-200 Energy Efficient Multicast through Acknowledgment based TPC in Adhoc Wireless Networks Department of Computer Science and Engineering Karpagam University, Coimbatore, India sangaviku@ Abstract The existing energy-aware routing algorithms in ad hoc networks, select a path with a large number of small-distance hops. But such a formulation based solely on the energy spent in a single transmission is misleading —the proper scheme should include the total energy (including that expended for any retransmissions necessary) spent in reliably delivering the packet to its final destination. Our main idea is to find a new routing scheme which is capable of including delay, energy, as well as link reliability factors to increase the operational lifetime of the network. The proposed analytical model successfully captures the key characteristic of a reliable power saving system: the data delivery procedure starts periodically at the previously negotiated time, but ends at a rather random time with its distribution depending on the end time of data delivery in the last delivery period as well as the arrival rate of incoming traffic. Keywords: Energy aware routing; Markov chain model; Ad hoc networks; reliable routing; routing protocols 1. Introduction Energy-efficiency and reliable routing are two important requirements in wireless ad hoc networks, where nodes have limited battery power and wireless links are prone to transmission errors. When nodes in the network cooperate to achieve a single goal (., in wireless sensor networks), maximizing the operational lifetime of the network is also an important requirement. While each of these requirements could be achieved separately in ad hoc networks, providing energy-efficiency and reliability in such a way that the network lifetime is maximized is of significance. Presently, there is no such .
