Physical Layer Design in Wireless Sensor Networks for Fading Mitigation
This paper presents the theoretical analysis, simulation results and suggests design in digital technology of a physical layer for wireless sensor networks. The proposed design is able to mitigate fading inside communication channel. To mitigate fading the chip interleaving technique is proposed. For the proposed theoretical model of physical layer, a rigorous mathematical analysis is conducted...
متن کاملCross-Layer Analyses of QoS Parameters in Wireless Sensor Networks
Providing reliable and timely information is one of the important tasks of wireless sensor networks. To this end, recently quality of service (QoS) satisfying end users and matching WSN constrains, has become an important research topic. However, majority of research in this area has overlooked the fact that ensuring quality of service requires a cross-layer approach spanning through all layers...
متن کاملMaster Synchronization in Physical-Layer Communications of Wireless Sensor Networks
Synchronization in physical layer of wireless sensor networks is critical in restricting complexity of tag node and power consumption. Considering the master-to-tag communication (i.e., receiving signal from a master or anchor node by tag nodes), we propose a scheme on the basis of the principles of feedback control, to transfer the signal acquisition functionality from the tag receivers to the...
متن کاملA Secure Routing Algorithm for Underwater Wireless Sensor Networks
Recently, underwater Wireless Sensor Networks (UWSNs) attracted the interest of many researchers and the past three decades have held the rapid progress of underwater acoustic communication. One of the major problems in UWSNs is how to transfer data from the mobile node to the base stations and choosing the optimized route for data transmission. Secure routing in UWSNs is necessary for packet d...
متن کاملRouting Hole Handling Techniques for Wireless Sensor Networks: A Review
A Wireless Sensor Network consists of several tiny devices which have the capability to sense and compute the environmental phenomenon. These sensor nodes are deployed in remote areas without any physical protections. A Wireless Sensor Network can have various types of anomalies due to some random deployment of nodes, obstruction and physical destructions. These anomalies can diminish the sensi...
