Abstract:

To import the response time factor into the routing mechanism of wireless sensor networks, the network architecture was refined, 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.

Key words: wireless sensor network, response time, routing mechanism
