Clustering In Wireless Sensor Networks: A Survey
نویسندگان
چکیده
Wireless sensor network (WSN) consists of large number of sensor nodes which perform their sensing, processing and transmitting tasks independently. Due to irreplaceable and limited battery life of the sensor nodes, energy consumption is the main hindrance in WSNs. Even in the presence of failures such as battery life depletion, node failures, etc., the energy of each node must be reserved for long run operation of the network. Clustering is the most popular method which can reduce energy consumption and improve scalability of WSNs. However, in a clustering algorithm, cluster heads (CHs) utilize more energy as they need to gather data from their clusters, aggregate this data and transmit it to the base station. Therefore, an efficient method for clustering is needed which can address the issues of energy consumption.
