Wireless network coding: An innovative technology

Network coding is a new technology that motivates us to rethink about networking in wireless networks. Network coding of wireless helps to improve the performance networks. The existing network infrastructure will not support to the network coding communications. This concept requires us modifying the existing network communications. In this paper we brief the principles of network coding, network coding techniques, benefits and applications. We also discuss the current research topics of interest and the issues related to network coding aware routing in wireless ad hoc networks and we also present the simulation results which describe the energy gain and number of transmissions in traditional routing versus network coding.
