文摘

Recently, large amounts of researches have demonstrated that dynamic changes of topological structure as well as unbalance of data traffic/energy consumption in wireless sensor networks have made routing protocol expansibility challenging work. According to the phenomenon that large-scale wireless sensor network will shorten longevity due to funneling effect in energy consumption; we proposed Unequally Clustering-based Hierarchical Opportunistic Routing (UCOR) protocol to reduce redundant network traffic. The protocol can further increase packets delivery ratio, decrease network delay and achieve more balanced and lower energy consumption. Experiment results show that UCOR protocol prolongs network longevity by about 20% to support for larger scale network, compared with HEED, EEUC, etc.
