Abstract

Wireless networks are becoming increasingly important in our daily lives. However, owing to noise of the wireless channel, attenuation, fading and interference from other devices, designing a reliable wireless transmission system is quite challenging. Current protocols use techniques like forward error correcting codes or ARQ to ensure reliability. My work seeks to implement a theoretical recently proposed protocol called Partial Packet Reception with Network Coding (PPRNC) using software defined radios. PPRNC is a novel cross-layer scheme that retains the non-compromised information of a partial packet, and attempts to recover the erroneous bits by using information from other valid packets. This enables higher throughput, increased reliability and potentially lower power consumption.
