通过分析现有无线传感器网络路由算法,结合大规模无线传感器网络的特点,提出了一种基于簇的分布式路由表簇内广播路由算法。详细介绍了簇间路由发现过程中簇内各节点间RREQ、RREP分组交互过程以及簇间路由算法,估计了簇间路由成本、路由表规模以及分组路由转发延迟。通过试验仿真验证,在增大网络规模的情况下,其路由表建立速度和路由规模上限均较传统算法具有明显的优势。

By analyzing existing routing algorithm for wireless sensor network,combined with characteristics of large-scale wireless sensor network,a distributed routing-table and broadcast in cluster routing algorithm based on cluster was proposed.The interaction of RREQ and RREP between nodes in cluster during the routing-discovery process and routing algorithm between clusters were also proposed.Later the cost of routing in cluster,the scales of routing-table and the delay of retransmit during routing process were calculated.The emulation results proved that this algorithm gains the advantage over traditional ones in aspects of routing-establishment rate and the limitation of routing-table scale.
