“…In recent years, interest in path loss modeling has risen significantly for the 2.4 GHz frequency [9][10][11][12][13]. In [14] a comparison of 6 major indoor RF models was performed, based on extensive measurements in residents and offices featuring operating Wi-Fi systems (802.11g protocol).…”

This paper presents a site-specific validation of path loss models for a complex indoor propagation topology at 2.4 GHz. More specifically, extensive RF measurements were performed at the Public Library of the University of Patras (for an operating 802.11g Wi-Fi system). The acquired average received power levels allowed us to validate the robustness of indoor RF models in terms of mean error and root mean-square error (RMSE) values and compare results with empirical data derived out of other commercial topologies. The shadowing deviation was empirically calculated as a function of path loss caused by all objects and materials contributing to the attenuation of the transmitted signal. Our findings confirm that in the presence of significant shadowing phenomena and signal obstruction as examined in this work, this novel method of sitespecific calculation of shadowing deviation, which can be applied for any frequency of interest as long as the respective signal losses are empirically estimated, is by far the most precise in terms of path loss prediction and link budget optimization.

“…Consequently, if the device gets lost, simply put it in the lock mode. The nLocator will allow you to put a four-digit pin that would block anyone from retrieving individual data from iOS when they are on and connected onto the Wi-Fi [13]. iPhone is not only who offers the Bluetooth based tracking facility, some other Bluetooth tracking systems also have been proposed and prototyped in academic [14][15], and some of the authors proposed an indoor accuracy of 1.5m [16].…”

“…The propagation model of ad hoc networks in indoor scenario like office, shopping mall and factory application depends on presence of large/small obstacles, wall, and furniture, etc., that effects EM wave propagation (Helhel, 2006;Iskander et al, 2001;Tarng and Liu, 1999). The generic model is employed here to investigate the path loss that highly depend density of the materials (Rao and Balachander, 2013;Yu, 2002).…”

Developing applications, especially real time ones mobile ad hoc network (MANET) requires a reasonable assurance of the likely performance of the network. MANET is realised by mobile nodes which communicate difficult task. Amongst many important properties of radio propagation model has to be selected carefully. This paper presents a hybrid propagation model of ad hoc network with multiple numbers of antennas. The hybrid technique ensures improved accuracy and practicality of the entire modelling environment. Currently study a modelled network consisting of ad hoc nodes with multiple antennas in different terrain and the propagation loss is calculated of the modelled network for the each ad hoc node. A loss less routing algorithm is implemented here and finally minimum loss route is selected for propagation in different terrain.
