The multi-hop wireless sensor network (WSN) suffers from energy limitation and eavesdropping attacks. Wepropose a simple and energy-efficient convergecast mechanism using inter-flow random linear network codingthat can provide confidentiality to the multi-hop WSN. Our scheme consists of two steps, constructing a logicaltree of sensor nodes rooted at the sink node, with using the Bloom filter, and transmitting sensory data encodedby sensor nodes along the logical tree upward to the sink where the encoded data are decoded according to ourproposed multi-hop network coding (MHNC) mechanism. We conducted simulations using OMNET++CASTALIA-3.3 framework and validated that MHNC outperforms the conventional mechanism in terms ofpacket delivery ratio, data delivery time and energy efficiency.
