The paper presents the criteria that affect the performance of network lifetime in Wireless Sensor Networks. In sensor networks the nodes can be organized into clusters for one hop energy-efficient data routing. This work focuses on adaptive clustering of sensor nodes where the role of cluster head changes among nodes. The nodes take turn to become cluster head based on one or several parameters such...
Wireless sensor networks are tiny devices with limited computation and energy capacities. For such devices, data transmission is a very energy-consuming operation. It thus becomes essential to increase the lifetime of a WSN by minimizing the number of bits sent by each device. One well known approach is to aggregate sensor data. Data aggregation is used to eliminate redundancy and minimize the number...
