摘要
为了把响应时间引入传感器网络中的路由机制,细分了网络层次,分析了响应时间模型、基于二层架构的传感器网络,制定了2种可行方案.新路由机制以现有节能路由算法为基础,根据时间约束修正路由路径和增添带有响应时间约束的路由表.分析结果表明,2种方案在计算复杂度和通信功耗上存在一个平衡,2种方案在实际传感器网络应用下是有效的.仿真试验表明,在路由机制中引入响应时间是必须的.
To import the response time the network architecture was refined, factor into the routing mechanism of wireless sensor networks, the response time model was analyzed and two feasible solutions based on two-tiered architecture were provided. Based on the energy efficient routing algorithm, in the new routing mechanisms, the routing paths were modified, and the routing table, according to response time restriction was decorated. The analyzing result can show that both the solutions, between which there exists a balance of computing complexity and communicating power consuming, are efficient. The emulating experiment verifies the necessity of importing the response time.
