A primary goal in the design of wireless sensor networks is lifetime maximization,constrained by the energy capacity of batteries.One effective method to reduce energy consumption in such networks is in-network data aggregation.This paper expatiates the concept of in-network data aggregation and two aggregation levels based on the characteristics of the wireless sensor network firstly.Then shows several data dissemination schemes related to the in-network data aggregation,and analyzeit how maximum delay T for data delivery affect the result of the in-network data aggregation when it is allocated to each aggregation node.
