A Routing Mechanism for Time Critical Applications in VSN

Abhishek Matmri, Sudhakar K N

Abstract: Visual sensor networks are emerging as a research technology and are deployed to get the visual data from the monitored field such as habitat monitoring, enriching monitoring and control applications. Set of camera are deployed to control sensor nodes to fetch the information from time critical monitoring and visual information such as images and video streams are sent to the destination node synchronously. Requiring a differentiated treating of the network when compared with non-critical visual data. In such way, we consider the source sensor nodes may have different sensing relevance mechanism for the application, based on the monitoring task and the current sensors poses and fields of view, In this paper we propose a delay-aware multihop routing mechanism where higher relevant visual data packets are routed through paths with lower end-to-end delay. As sensor nodes are expected mainly depends on energy, transmitting only high relevant packets through shorter/faster paths may prolong their lifetime and assure longer time-critical delivering, with low impact to the overall monitoring quality. In simulation with NS2 we shown sending of high relevance data on delay aware sensor network. .
