Abstract: Network Coding (NC) has been applied in Wireless Sensor Networks (WSNs) where major improvements have been achieved. In this paper, we propose a network coding routing mechanism in WSNs that is based on Vector-Based Forwarding (VBF). The goal of the proposed routing mechanism is to decrease the total number of transmissions needed to deliver data to the destination. Decreasing the total number of transmissions is achieved by varying the number of transmissions performed by each sensor node in a particular way that does not sacrifice the reliability of data delivery. Decreasing the number of transmissions decreases the traffic forwarded in the process of delivering data and enhances power savings which prolong the lifetime of the WSN. Simulation results show major improvements achieved by the proposed routing mechanism.
