Abstract

Wireless multimedia sensor networks will have a variety of applications. Meanwhile, WMSNs produce a large amount of image data. JPEG2000 is the popular image compression standard and have some advantages. However, JPEG2000 is also high complexity and cannot be realized in an individual senor node which is limited in memory capacity, computation power and energy. Distributed image compression and transmission scheme is proposed to overcome the problem of scarce resources of the individual sensor node and uneven energy consumption. Simulation experiments show that DICT can more evenly consume the energy of senor nodes in WMSNs and prolong the network lifetime comparable to centralized image compression and transmission scheme. DOI : http://dx.doi.org/10.11591/telkomnika.v12i1.3739

Abstract

Multi-path routing protocols have many advantages in wireless multimedia sensor networks. To succeed in setting up multiple paths in the wireless multimedia sensor network, the Adaptive Deployment Scheme of sensor Nodes which is based upon multi-path routing protocol (ADSN) is proposed in the paper. ADSN deploys the sensor nodes on the basis of the number of paths, camera nodes’ positions and the sink’s position etc. Compared to the uniform deployment scheme, ADSN can save 67% sensor nodes when setting up multiple paths. And it can avoid the hotspot area in the vicinity of the sink. Energy Equalization Multi-path Routing protocol (EEMR) can consume the energy of sensor nodes more evenly and extends the network lifetime compared to TPGF. DOI : http://dx.doi.org/10.11591/telkomnika.v12i2.3820
