An Energy Based Clustering for Data Gathering using Multiple Sensor Cars in WSN

Nowadays, Data Gathering using mobile element plays an important role in wireless sensor network. The mobile element can gather data in two ways. First, Data can be collected from the sensor nodes using single hop relaying. This maximizes the energy consumption and minimizes the lifetime of the network. Secondly, the data can be collected using Multi-hop relaying scheme. This minimizes the energy consumption of a single sensor node and maximizes the network lifetime which in turn reduces the data loss and minimizes the delay. But there is a problem on routing the data packets from sensor node to base station. This paper proposes an Energy based Clustering for Data Gathering Using Multiple Sensor Cars (EC-DGMSC) in Wireless Sensor Networks which assembles the sensors into group and an aggregation node (Cluster Head-CH) is elected for each group. The Sensor Car (SenCar) gathers data dynamically from the CH, once the energy level of CH falls below the threshold then new CH will be selected from the cluster. Thus, the proposed framework reduces the energy consumption of the sensors as well as extends the network lifetime compared to existing systems.
