摘要
In this paper, we study the problem of correlated data gathering in wireless sensor networks. An opportunistic routing protocol joint with opportunistic network coding is proposed for correlated data gathering. In order to reduce the total transmission, we introduce the expected number of coded transmission (ECTX) as metric for the routing selection. Moreover, we also define the coding gain for the network nodes to count the coding opportunistic, with which the throughput of the wireless sensor network is further increased. Numerical simulations are conducted for performance analysis with the proposed routing scheme.
