EEHC: Event-driven Energy Optimization in Heterogeneous Clustered Wireless Sensor Networks

Wireless sensor networks are used in various applications worldwide. Large numbers small sized, inexpensive, low-powered sensor nodes are deployed in the target field to monitor or track particular objects. Sensor nodes have limited energy and computation capability. Energy optimization is an important task should be performed to improve the lifetime of the wireless sensor networks. Many researches focus only on continuous delivery model. This paper proposed energy efficient event-driven heterogeneous clustered wireless sensor network (EEHC) system. The results show that the proposed system reduced the energy consumption and longer lifetime than its comparatives
