Combining Network Coding (NC) with flooding routing protocols has been proven beneficial in Delay Tolerant Networks (DTNs). This paper focuses on efficiently using the constrained energy of DTN nodes by enhancing NC with an effective memory management algorithm (MMA). Upon having received a sufficient number of linearly independent packets resulting in a matrix of full rank, the destination nodes can apply network decoding. As the network nodes make decisions based on information collected solely from their own buffer, the NC/MMA scheme employed is fully distributed. Employed combinedly either with Epidemic or with probabilistic routing protocols in energy constrained DTNs for nodes equipped with either Zigbee or Wifi interfaces, the scheme manages to drastically reduce the aggregate transmit energy while slightly improving the packet delivery probability.
