Network Coding (NC) is confirmed to be power and bandwidth efficient technique,\nbecause of the less number of transmitted packets over the network.\nWireless Sensor Network (WSN) is usually power limited network application,\nand in many scenarios it is power and bandwidth limited application.\nThe proposed scenario in this paper applies the advantages of NC over WSN\nto obtain such power and bandwidth efficient WSN. To take the advantages of\nNC over the one of the most needed applications i.e. , WSN, we come up to\nwhat this paper is discussing. We consider a WSN (or its cluster) that consists\nof M nodes that transmit equal-length information packets to a common destination\nnode D over wireless Rayleigh block-fading channel where the instantaneous\nSNR is assumed to be constant over a single packet transmission\nperiod. Finite-State packet level Markov chain (FSMC) model is applied to\ngive the channel more practical aspect. The simulation results showed that\napplying NC over the WSN cluster improved the channel bandwidth significantly\nby decreasing the number of the Automatic Repeat Request (ARQ), resulting\nin improving the power consumption significantly. The results are\ncollected for different transmission distances to evaluate the behavior to the\nproposed scenario with regard to the bath losses effect.
