In this paper, we present a detailed analytical study of previously proposed variable preamble length-based broadcasting scheme for wireless sensor networks (WSNs). Analytical results show that in dense wireless sensor networks, broadcasting a packet with a small size preamble can significantly improve the energy conservation on already limited battery powered sensor nodes. For fairer compariso...

the effect of evaporation rate on structural, morphological and optical properties of electron beam evaporated cds thin films have been investigated. cds thin film deposited by electron beam evaporation method in 12nm/min and 60nm/min evaporation rates on glass substrates. x-ray diffraction, scanning electron microscopy, uv-vis-nir spectroscopy and atomic force microscopy were used to character...

for button mushrooms packaging, the packaging films with high permeability to oxygen and carbon dioxide are required. permeability of plastic films such as pvc lead to loss of weight (and thus economic value) and textural changes are undesirable for button mushroom. so packaging film of polyolefins (pd 941 and pd 961) can be used. also the new film, hydrophilic materials such as films made from...

Recently, a huge effort has been pushed to the wireless broadcasting nature in open area. However, vehicular ad hoc network (VANET) is disposed various kinds of attacks. Hence, keeping security VANET most critical issue because related human life. Thus, we propose robust and lightweight key agreement-based identity protocol LSKA-ID for communication. Our utilizes elliptic curve cryptography, Ch...

Security is an important factor that cannot be neglected in the design of time synchronization algorithms since industrial wireless sensor networks are prone to attacks against physical nodes and communication links. The Sybil attack intelligent with a high destructive capacity pretending multiple identities broadcasting illegitimate messages destroy network operation. Existing secure mostly fo...

Recent works have classified de Bruijn graph (dBG) based broadcasting algorithms into local broadcasting and arc-disjoint spanning trees based broadcasting. However, those algorithms can only work in binary dBG. In this paper, we investigate broadcasting in bidirectional dBG for a degree greater than or equal to two. A distributed broadcast algorithm for one-to-all broadcasting in the all port ...

Many factors influence physical properties of edible composite films fabricated from hydrocolloids and lipids. Novel edible emulsified films were made using PGP, glycerol and stearic (SA) or oleic (OA) fatty acids by Tween-80 addition and emulsification of filmogenic solutions. In this study, the effect of physical state of fatty acids on the pistachio globulin protein (PGP) edible film prop...
