A partial network coding scheme based on energy-balancing in WSN

Abstract

This paper provides a new partial network coding scheme suitable for WSN. The sensor nodes of this scheme include four states: Normal, Coding, Suspend and Sleep. Transformation between these states is energy-oriented and relevant scheme are divided into three steps: Initiate coding, Check Period and Balance energy. First, the paper describes the designing process of this scheme, and then describes the coding and decoding process of random linear network coding used in this paper. At last, according to the result of the NS2 virtual experiment, this scheme exceed traditional network coding schemes: increasing the efficiency of network resource usage, decreasing network lag and expanding living period of WSN. © 2012 Springer-Verlag GmbH.
