Research on TEEN with network coding

Abstract

For traditional routing model in wireless sensor networks (WSN), the function of intermediate nodes is storage and forwarding. Due to the limitation of WSN in energy, capability of communication, computing and the capability of storage, it is difficult for nodes to communicate. Existing researches show that using network coding in WSN can enhance throughput and the security transmission of network, and reduce the energy consumption of nodes [1]. This paper chooses a typical TEEN protocol as the research object of network coding. We attempt to employ network coding to achieve the improvement on throughput of WSN and communication performance, and decrease the energy consumption of sensor nodes. Based on these points, this paper proposes to create network coding opportunities on cluster head nodes in TEEN protocol by utilizing the advantages of opposite links, and a new network coding model basing on TEEN (NCTEEN). The results of simulations show that NCTEEN model has better performance than TEEN in terms of throughput and energy consumption. To be specific, the throughput and performance of network are improved and the energy consumption in cluster head nodes is reduced.
