The lifetime of the wireless sensor network is treated as a concerning topic for every network related application as the sensors are provided with limited battery capacity. In order to improve the network life, the energy of the nodes should be utilized in a well-organized way. The existing cluster-based routing protocols and data aggregation approaches have helped in enhancing the network's lifetime. The data aggregation approaches minimize the redundant data packets in the network which improves the network lifespan. In this paper, a cluster-based routing scheme for heterogeneous network (CRSH) is proposed which performs the clustering of nodes and data aggregation in the network. The proposed scheme uses the node’s energy level for choosing the most energy-efficient node as cluster head and performs the data aggregation to eliminate the redundant data packets. The simulation of the proposed scheme is performed in the MATLAB simulator. The proposed scheme is compared with the existing protocols using various performance parameters for measuring its effectiveness.

由于传感器具有有限的电池容量，因此无线传感器网络的寿命被视为每个网络相关应用的关注主题。为了提高网络寿命，应该有条理地利用节点的能量。现有的基于集群的路由协议和数据聚合方法有助于提高网络的生命周期。数据聚合方法最大限度地减少了网络中的冗余数据包，从而提高了网络寿命。在本文中，提出了一种基于集群的异构网络路由方案（CRSH），该方案在网络中执行节点的集群和数据聚合。所提出的方案利用节点的能量水平来选择最节能的节点作为簇头，并执行数据聚合以消除冗余数据包。所提出的方案的仿真是在 MATLAB 仿真器中进行的。所提出的方案与使用各种性能参数来衡量其有效性的现有协议进行了比较。
