Path loss is caused by the propagation characteristics and the obstacles between transmitter and receiver due to which signal strength is reduced in wireless communication. Analysis based on path loss models provides good initial estimate of the signal characteristics. Propagation models are used to determine the path attenuation based on parameters such as carrier frequency, transmitter-receiver distance, basestation antenna height, receiver antenna height and terrain profile (e.g. rural, suburban and urban). Propagation models are used for path loss estimation which is important for planning the deployment of base-stations and area of coverage. In this paper, different Propagation models such as Okumura's Model, Hata Model, Longley rice Model, Free Space Propagation Model, COST 231 Extension to Hata Model, COST 231 Walfisch Ikegami Model, Stanford University Interim (SUI) Model and Hata-Okumura Model are surveyed. A comparative analysis of these models is provided which can serve as a valuable guide for selecting the appropriate model for a specific application scenario.

High-rise commercial and residential buildings are very common in today's modern cities and are subject to fires and gas leaks. When such buildings collapse, however, it is imperative that methods for the rescue and evacuation of residents be considered. This paper mainly focuses on detecting potential occurrences of cascading disasters due to fires and gas leaks in a collapsing building by frequently communicating with an Incident Management System via a wireless sensor network and UAVs. Using QualNet, an in-depth study of various antenna options and their characteristics is done and the selection of a suitable antenna, based on this study, is discussed. The network characteristics of ZigBee at different operating frequencies are also analyzed. Furthermore, an algorithm is proposed to deploy a wireless sensor network to detect fires, gas leaks, etc., using minimal number of ZigBee nodes. More »»
