Various Methods of Link Design for Transferring Data in Wireless Sensor Networks for different Applications

Abstract

This paper offers the different type transmission schemes used in wireless sensor networks. The wireless sensor network used in a number of applications such as Agriculture, Military, Medical, Multimedia etc. According to the applications there are different quality of service parameters and designing requirements for different layers in network design. While designing any ad hoc network or sensor network many designing principals and challenges are taken into consideration. For the designing of protocols layering in ad hoc sensor network basically a five layer model is taken into consideration. These layers are application, transport, network, Medium access control and physical layer. In this paper different types of designing constraints associated with physical and medium access layer has been introduced for different applications in sensor networks. In that manner this paper helps us to select the designing of a link for particular application.

QoS Strategies for Wireless Multimedia Sensor Networks with Energy- Efficient Routing Techniques & QoS Assurances

“…Min Chen et al, [34] focused on the problem of real-time streaming video over energy and constrained bandwidth WSN with a small volume of Video Sensor Nodes (VNs). This approach applied FEC [35] along with a novel multipath routing scheme called "Directional Geographic Routing (DGR)". After encoding the FEC secure H.26eL real-time streaming video data, DGR establishes an application that required multiple disjoint paths for a VN to sink.…”
