Wireless multimedia sensor networks (WMSNs) are expected to find wide applicability in target tracking in the near future. This paper proposes a dynamic capacity multi-path routing protocol (DCM), based on improved Ford-Fulkerson algorithm, to solve the problem of data transmission from anchor nodes to base station (BS). By adjusting the parameter of flow capacity in max-flow model, a multi-path routing...
The existing routing protocols designed for real-time multimedia applications in sensor networks adopt comparatively simple routing models where fewer service metrics are considered. Furthermore, for the sake of route discovery or the acquisition of a target location, they usually need extra locating equipments or beacon exchanges to construct a coordinate system for each sensor node, which imports...
Recently, the focus of sensor network paradigm is changing for delivering multimedia contents such as audio and video streams and still images. However, most existing routing protocols are not very practical for transmitting multimedia contents in resource constrained sensor networks. In this paper, we propose an optimized nod-disjoint multi-path routing scheme resulting in throughput enhancement...
Wireless sensor networks consisting of spatially distributed autonomous devices required to survive in unprotected environments. They are always susceptible to attack by malicious behavior of its routers (nodes) or external enemy nodes which could negatively affect secured routing and QoS and hence, vital wireless multimedia applications. In recent times, a lot of specific severe attacks have been...
