提出一种基于属性相关的异构数据融合路由策略使无线传感器网络寿命最大化.该策略的基本内容是:1)通过将相同属性的感知数据路由到同一个环形路由上,这样可以使不同属性的数据进行充分融合,从而减少数据冗余最小化所需传输数据,节省节点能量;2)依据无线传感器网络的远Sink能量消耗低、近Sink能量消耗高的特征,将数据融合环形路由建立在远Sink区域,这样充分利用远Sink区域的剩余能量,且同一属性的数据沿环形路由1周,使数据融合达到最大化,从而使需要发送到Sink的数据量极小化.通过模拟与理论分析结果验证策略的有效性.研究结果表明:本文策略是有效的,能极大地提高网络寿命.%A correlation attributes based on heterogeneous data fusion routing(CADFR) scheme was proposed to maximize network lifetime for WSNs. The main features of CAFR scheme are as follows. 1) Routes the data with the same attribute to the same ring routing path, so the data fusion can be fully used, the redundancy transmission can be eliminated, and the node's energy can be saved. 2) Considering the feature of WSNs is that the energy consumption of wireless sensor networks is low near the Sink and high faraway the Sink, the ring routing path is built in far Sink area which can make full use of the surplus energy far Sink region. On the other hand, the data of the same attribute routes a circle along a ring route, which furtherly eliminates redundancy data. Both theoretical computation and simulation were used to verify the effectiveness of the scheme. The results show that the proposed scheme is effective, and can significantly improve the performance of network.
