Flood Routing Based on Network Coding (NCF)
Most of the energy in a sensor network is used for transmission of data packets. For this reason, optimization of energy consumption is of utmost importance in these networks. This paper presents NCF, a flood routing protocol based on network coding. Simulations show that in addition to eliminating the drawbacks of traditional flooding methods, like the explosion phenomenon, NCF increases the lifetime of the network by at least 20% and decreases the number of packet transmissions. Another advantage is increased reliability and higher probability of data packet retrieval due to coding of information as logical operations and simplicity of implementation in sensor nodes.
