Reliable data transport has always been one of central issues in the area of communication networks. In this work, we investigate the possibility of enhancing reliability of selective repeat (SR) automatic repeat request (ARQ) by integrating network coding techniques into it. Through extensive simulation experiments, we analyze packet transport performance, e.g., throughput and delay, against various parameters including network transmission delay, packet loss rate, etc. Based on findings through simulation experiments, we then suggest design and operation guidelines and address harmonizing issues in integrating SR ARQ and network coding.

CNT/LiNi 0.33 Mn 0.33 Co 0.33 O 2 nanocomposite electrode material was fabricated for Lithium Ion Battery. Sol-Gel synthesis has been used to synthesize the nano-sized pristine LiNi 0.33 Mn 0.33 Co 0.33 O 2 (LNMC). CNT/LiNi 0.33 Mn 0.33 Co 0.33 O 2 nanocomposite has been synthesized by using low temperature dispersion method. Structural characterization of the material has been performed by using X-ray diffraction, which shows the formation of single phase LiNi 0.33 Mn 0.33 Co 0.33 O 2 with R-3m as space group. Morphological properties have been investigated by using characterization tool such as FESEM, which confirms the formation of composite material. Thermal properties have been characterized by DSC/TG measurements. Electrochemical performance of the material is under study. CNTs helped in increasing the cycle life of the material when cycled in the voltage range of 4.6-2.8V at a cycling rate of 0.2 mA/cm2, however the impedance is found to be higher in case of the composite material compared to the pristine nano-sized LNMC.
