针对异构传感器网络,提出了基于N∶X数据聚合的数据传输路由算法,对节点要传输的数据按照N∶X(X=1,2,3)的聚合比例进行聚合以达到延长网络寿命的目的.该算法减小了网络节点传输的数据量,保护了目的节点附近的能量消耗.仿真结果表明,基于数据聚合的数据传输算法在异构网络中能更好地延长网络寿命,提高网络的性能.

Aiming at heterogeneous sensor network, N ： X-based data aggregation routing algorithm was proposed, data transferred is aggregated by N ： X （X： 1,2,3） to prolong the network life. The algorithm reduces the size of data transferred to protect the nodes near the destination node. The simulation results show that the data transmission algorithm based on data aggregation in the heterogeneous network can prolong the network lifetime better, improve the performance of network.
