In wireless sensor networks, nodes are power-limited, hence, we need to save the energy of nodes to guarantee the operations of the network. In this paper, the energy consumption of nodes in the process of node location estimation is reduced by allocating the transmission power of the anchors. Based on the mathematical model of Direction of Arrival (DoA) estimation error variance as a function of...
Node localization plays a fundamental role in wireless sensor networks (WSNs). The distance vector hop (DV-Hop) algorithm is one of the best localization algorithms because of its low complexity, low cost, and simplicity. However, the localization accuracy can be poor when the number of anchor nodes is low. To improve this accuracy, a weighted DV-Hop algorithm based on the received signal strength...
Designing and practical implementation of energy efficient routing protocol is always a major concern for researchers in Wireless Sensor Networks (WSNs). In the past decade various energy efficient clustering routing protocols are designed to overcome this issue. Clustered base path planning technique is widely used in both homogeneous and heterogeneous WSNs. Existing techniques are based on direct...
