Reliable Network Coding for ZigBee Wireless Sensor Networks

Résumé

It has been analytically and empirically proved that Network Coding can significantly enhance wireless communications in terms of achievable throughput, data delivery and delay. While research in Network Coding has mainly ad dressed the problem of coding efficiency, buffer optimization and queuing, little attention has been paid to what we define as coding reliability, i.e., the ability for nodes to encode packets efficiently enough, so that a maximum number of its destinations can extract innovative data whatever the medium conditions can be. In this work, we investigate this concept in Wire less Sensor Networks (WSN) then we present Re-CoZi, a pack et transport mechanism which enables robust XOR Coding for WSN using echo-feedback packet reception and decoding acknowledgement. Our performance analysis shows that Re CoZi keeps the added value of NC in terms of bandwidth utilization and delay, while providing a more reliable coding.
