摘　　要：基于Mesh-under和Route-over这两种6LoWPAN(IPv6 over Low-Power Wireless Personal Area Networks)无线网络路由协议的优点,并针对前者扩展性差,后者复杂度较大等不足,提出一种新的路由协议S-RPL(Simple IPv6Routing Protocol for Low-Power and Lossy Networks)。S-RPL协议按需驱动、寻址路由,每个节点只保存附近两跳内的节点信息,同时优化Rank值计算,还继承了Route-over机制中互联网的通用性、可扩展性。如此,S-RPL中节点地址存储量小,节点的运算开销低、能量消耗低,且能寻找最优、跳数最少的路径。NS2仿真结果表明该协议具有低功耗的优点。Based on the advantages and disadvantages of wireless sensor network routing protocol for the 6 LoWPAN（ IPv6 over Low-Power Wireless Personal Area Networks）,Mesh-under and Route-over,this paper proposes a new routing protocol named S-RPL（ Simple IPv6 Routing Protocol for Low-Power and Lossy Networks）. And this kind of protocol improves the poor extendibility of Mesh-under and the complexity of Route-over. The S-RPL protocol is an on-demand driven protocol as well as an addressing-based routing protocol,and it just stores node information of two-hop neighbours,optimizes the calculation of Rank,inherits the universal property and extendibility of Route-over mechanism. Thus,the storage of node address in S-RPL,the computation and the consumption energy of nodes are reduced.Meanwhile,the S-RPL protocol looks for the best path or the path with least hops. The simulation of NS2 shows that the S-RPL implements low-power.
