Video streaming over wireless sensor networks

With WSN technologies becoming more reliable, sophisticated and more capable of meeting the demands of market opportunities and with its broad applications and new emerging trends like: internet of things and integrated web-based services, there still a need for developing protocols to manage and improve coherence and consolidation of the network. Video sensing can be involved in most of the WSN applications like: military, environmental, healthcare, industries and surveillance of all its types, where WMSN came as an important trend of WSN. In this paper an available zigbee-based WSN system model was used, a video source was integrated into it representing a video sensing unit. A network topology of video source node, scalar source node, sink node and a coordinator is presented. The work aims to centralizing control and network management functions at the coordinator removing some loads from other nodes utilizing more resources for data transmission and reception. The results show that QoS supported video transfer can be achieved by the mentioned system under moderate video parameters.
