Shengbin Liao · Chuangan jishu xuebao · 2008
In data-centered wireless sensor networks, the problems of information exchange among nodes have attracted more and more interests of researchers. The efficiency of information exchange reflects the network quality of service, even affects the lifetime of networks. Based on clustered sensor networks, the intra-cluster nodes topology models are proposed with some intra-cluster information exchange algorithms. More specially, the network coding algorithm is discussed in detail. After theoretical analysis and packet-level simulation comparison, the advantages and disadvantages of the traditional algorithms and network coding algorithm are summarized. The open research issues in this field are also pointed out.
