realistic mobility models can demonstrate more precise evaluation results because their parameters are closer to the reality. in this paper a realistic fuzzy mobility model has been proposed. this model has rules which are changeable depending on nodes and environmental conditions. it seems that this model is more complete than other mobility models.after simulation, it was found out that not o...

Adaptive networks include a set of nodes with adaptation and learning abilities for modeling various types of self-organized and complex activities encountered in the real world. This paper presents the effect of heterogeneously distributed incremental LMS algorithm with ideal links on the quality of unknown parameter estimation. In heterogeneous adaptive networks, a fraction of the nodes, defi...

  This paper proposes a new structure for digital address decoders based on flip-flops with application in wake-up signal generators of wireless networks nodes. Such nodes equipped with this device can be utilized in Internet of Things applications where the nodes are dependent on environment energy harvesting to survive for a long time. Different parts in these wireless nodes should have an e...

ChipCon radio is the radio chip that has been used recently for wireless sensors in Berkeley NEST group. ChipCon radio generates an analog signal indicating the signal strength of the received data bits and we used this signal strength as a tool for localizing sensor nodes. We modified the network stack of DOT3 sensor nodes to make the signal strength available. Experiments showed that the sign...

Wireless sensor networks attracting a great deal of research interest. Accurate localization of sensor nodes is a strong requirement in a wide area of applications. In recent years, several techniques have been proposed for localization in wireless sensor networks. In this paper we present a localization scheme with using only one mobile anchor station and received signal strength indicator tec...

introduction: lymphoscintigraphy is imaging of the lymphatic system and has been integrated into the sentinel node mapping procedures. lymphoscintigraphy usually encompasses early or delayed static images. however, immediate dynamic imaging of the lymphatic basins and tumors has also been used as an adjunct lymphoscintigraphy imaging. the aim of this study was to assess the role of early dynami...
