However, it suffers from the limited capacity of wireless communication and a network is easily overflown with a considerable amount of video traffic. In this paper, we propose an autonomous video coding rate control mechanism where each camera sensor node can autonomously determine its coding rate in accordance with the location and velocity of target objects. For this purpose, we adopted a biological model, i.e., reaction-diffusion model, inspired by the similarity of biological spatial patterns and the spatial distribution of video coding rate. Through simulation and practical experiments, we verify the effectiveness of our proposal.<\/jats:p>","DOI":"10.3390\/s100807651","type":"journal-article","created":{"date-parts":[[2010,8,13]],"date-time":"2010-08-13T10:53:31Z","timestamp":1281696811000},"page":"7651-7673","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["A Reaction-Diffusion-Based Coding Rate Control Mechanism for Camera Sensor Networks"],"prefix":"10.3390","volume":"10","author":[{"given":"Hiroshi","family":"Yamamoto","sequence":"first","affiliation":[{"name":"Graduate School of Information Science and Technology, Osaka University, 1-5 Yamadaoka, Suita, Osaka 565-0871, Japan"}]},{"given":"Katsuya","family":"Hyodo","sequence":"additional","affiliation":[{"name":"Graduate School of Information Science and Technology, Osaka University, 1-5 Yamadaoka, Suita, Osaka 565-0871, Japan"}]},{"given":"Naoki","family":"Wakamiya","sequence":"additional","affiliation":[{"name":"Graduate School of Information Science and Technology, Osaka University, 1-5 Yamadaoka, Suita, Osaka 565-0871, Japan"}]},{"given":"Masayuki","family":"Murata","sequence":"additional","affiliation":[{"name":"Graduate School of Information Science and Technology, Osaka University, 1-5 Yamadaoka, Suita, Osaka 565-0871, Japan"}]}],"member":"1968","published-online":{"date-parts":[[2010,8,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"393","DOI":"10.1016\/S1389-1286(01)00302-4","article-title":"Wireless Sensor Networks: A Survey","volume":"38","author":"Akyildiz","year":"2002","journal-title":"Comput.
