A survey on wireless multimedia sensor networks
The availability of low-cost hardware such as CMOS cameras and microphones has fostered the development of Wireless Multimedia Sensor Networks (WMSNs), i.e., networks of wirelessly interconnected devices that are able to ubiquitously retrieve multimedia content such as video and audio streams, still images, and scalar sensor data from the environment. In this paper, the state of the art in algo...
متن کاملCongestion Control Approaches Applied to Wireless Sensor Networks: A Survey
Wireless Sensor Networks (WSNs) are a specific category of wireless ad-hoc networks where their performance is highly affected by application, life time, storage capacity, processing power, topology changes, the communication medium and bandwidth. These limitations necessitate an effective data transport control in WSNs considering quality of service, energy efficiency, and congestion control. ...
متن کاملA Survey of multimedia streaming in wireless sensor networks: progress, issues and design challenges
Advancements in Complementary Metal Oxide Semiconductor (CMOS) technology have enabled Wireless Sensor Networks (WSN) to gather, process and transport multimedia (MM) data as well and not just limited to handling ordinary scalar data anymore. This new generation of WSN type is called Wireless Multimedia Sensor Networks (WMSNs). Better and yet relatively cheaper sensors – sensors that are able t...
متن کاملA Fuzzy Based Approach for Rate Control in Wireless Multimedia Sensor Networks
Wireless Multimedia Sensor Networks (WMSNs) undergo congestion when a link (or a node) becomes overpopulated in terms of incoming packets. In WMSNs this happens especially in upstream nodes where all incoming packets meet and directed to the sink node. Congestion in networks, if not handled properly, might lead to congestion collapse which deteriorates the quality of service (QoS). Therefore, i...
متن کاملA Survey of Coverage analysis in Wireless Multimedia Sensor Networks
Due to random deployment of camera nodes in wireless multimedia sensor network (WMSN) to cover surveillance area [1], there will be increase in overlapped field of view (FOV) and redundant transmission [2] of images in the network. This leads to increase in bandwidth utilization and reduce the network lifetime. This article concentrates on survey of node deployment strategies in WMSN to provide...
