Multimedia Communication in Wireless Sensor Networks — A Review Paper

Abstract

In recent years, the advances in wireless communications have given rise to the concept of wireless sensor networks (WSN) and wireless multimedia sensor networks (WMSN), which contain smaller, cheaper and multifunctional sensor nodes. These tiny sensor nodes; equipped with cameras, microphones, and other sensors which produce multimedia content, communicate in short distances and fulfill the specific aims of WMSNs. Therefore, acknowledgment of the extensive class of imagined WMSN applications needs proficient correspondence conventions, which can meet the interesting difficulties confronted by WMSN applications. Since a number of these applications gather data as media, for example, sound and feature streams, pictures, and so forth. Remarkable difficulties because of the unique necessities of media correspondence over WSN, e.g., dependability and time imperatives, high-transmission capacity requests, must be dealt with too. Therefore, a lot of research literature in the recent years has been pointed towards finding the solutions of conventional data communication in WMSNs. In this paper, we presented the challenges and the latest research being done in the research community for meeting the challenges in WMSNs. This research paper emphasizes on routing approaches for WMSNs and gives a review of the most critical difficulties and inclinations as to steering conventions for WMSNs, media and system execution. Because of the vitality of the steering plans and sight and sound mindfulness conveyance in streamlining operations, a specific consideration will be given around there. Various distinctive methodologies to media directing will be talked about to clarify the way of these difficulties.
