Embracing Wireless Interference: Analog Network

Basically, in a wireless network there are ’n ’ nodes where they send and receive packets each other. Generally, for every network, throughput gain is more important. In order to improve the throughput multiple transmissions should occur simultaneously. But, if the network sends packets simultaneously, packet collision occurs. Packets may interfere at any node. Generally, this kind of interference is not supported by tradition approach because of collision. In contrast, this paper supports interference in which it allows the senders to transmit signal simultaneously which results an interfering signal. The interference is supported by using Analog Network Coding approach which is done at physical layer. Analog network coding is widely used in many applications such as video conference, mobile networks and voice conversation between two peers. This paper presents modulation/demodulation scheme which is used for designing analog network coding. Later the paper will discuss about how analog network coding approach increases throughput by comparing with others approaches and also the paper presents some future works on this approach in order to improve the efficiency. Finally, the paper concludes analog network coding approach by proving that this approach improved in throughput gain compared with other approaches.
