摘要：Transmissions are costly in wireless sensor networks due to energy constraints in sensor nodes. In this work we apply network coding in WSNs that use Vector Based Forwarding (VBF) as a routing protocol. The goal is to decrease the total number of transmissions performed to deliver data. The proposed forwarding mechanism is location based. This means that the number of transmissions performed by a node depends on the location of that node within the VBF routing vector. Through simulations we evaluate the proposed forwarding mechanism. Results indicate major improvements in the total number of transmissions needed and the amount of traffic generated while propagating data to destination reliably.
