With the advancement in sensing technology, applications are moving from wired to wireless region. The main challenge is the energy consumption of individual sensing nodes. When first node dies system becomes unstable and we cannot make use of the untapped node's energy. There comes the relevance of TSEP like protocols in such heterogeneous network. Heterogeneous in the sense with respect to node energy the system becomes unstable. This work analyzes the advantages of TSEP like protocols. When we are manufacturing application for predicting the environmental pollution, natural and ecological disasters, all need to be communicated at present. So energy of sensing node places a crucial factor. The primary source of a sensor node is usually a battery and is usually neglected once it is deployed, which creates routing decision problem and scalability issues. In this work, the data acquisition happens by using a temperature sensor application, the proposed work captures data and it is analyzed using stable election protocol by observing the output performance with respect to lifetime of sensing nodes.

The heterogeneous networks are those which can connect different devices running with different operating systems and using different protocols. The main problem with these networks is network connectivity. In order to ensure the continuous network connectivity between the nodes, the Delay Tolerant Networks (DTNs) are useful as they operate on extreme distances and depend up on the changing positions of the nodes. The Epidemic Routing Protocol (ERP) makes use of DTN concept. The previous works show the performance of Epidemic Routing Protocol in terms of packet delivery ratio, end-to-end delay, and energy consumption. In this work, the Epidemic Routing Protocol's performance for Delay Tolerant Networks will be evaluated by considering different parameters like, Average Latency, Energy Balancing Factor, and Number of Alive and Dead nodes.

As degradation of signal issue become critical in today's communication medium. So prediction of correct path loss is important for GSM radio network planning to estimate network interference level and cell planning deployment accurately. GSM (Global System Mobile Communications) signal throughput and coverage range is one of the most important factors that will impair the quality of broadband wireless systems [2]. The study focused on shadowing effect in urban (combination of green vegetation and high raised buildings) terrains for propagation characteristics of GSM systems. A GSM frequency 950 MHz used for this experiment in a typical urban terrains. The measurement results compared with Cost-walfisch Ikegami model, Okumura Hata model and Bertoni-walfisch model. Finally, the results show that Bertoni model is better for predicting the path loss in tall buildings. The results are obtained using MatLab simulation software.

Radio propagation in wireless communications varies based on the speed of frequency operation, mobile terminal and the parameters like, transmitter antenna height, mobile height, connector loss, cable loss, antenna gain, path losses and receiver sensitivity. The Path loss and the parameters of the transmitter (TX) and receiver (RX) depend on the received signal strength. The establishment of the quality of call is based on received signal strength. Signal strength varies based on different terrains. In this paper, Cost-Hata model, ECC-33 model and Ericsson models are considered for Path loss calculation [2]. The different receiver antenna heights (1.5m and 10m) of signal strength is calculated and compared with proposed propagation models for different terrains.

In recent days the Worldwide Interoperability of Microwave Access (Wimax) technology has become popular and receives acceptance as a broadband wireless access (BWA) system [5]. Wimax communication, which enables transmission of voice and data wireless in urban and highway environments [5]. In this study we considered, Wimax frequency 2.6 GHz and 3.5 GHz in urban and highway for RSS terrains [2]. RSS(Receiving Signal Strength) to measure the power between base station(BS) and mobile station(MS)[8]. RSS becomes efficient coverage, when base station proximity near to mobile station [8]. RSS deteriorates, when mobile station moves far from base station. Variation in signal strength from transmitter(Tx) and receiver antenna (Rx) would be considered as path loss [8]. In our work, the analysis is done using MAT Lab simulation software. With different path loss models, considering urban and highway terrains with RSS for given WiMax frequency in SIMO (Single Input Multiple Output) channel[5]. We have proposed ECC model is better since this model supports frequency greater than 3.0 GHz [2].

Now-a-days broadband wireless access system supports potential success in radio network planning. In this paper we have considered GSM and WIMAX cellular network with different operating frequencies in wireless broadband services. The critical task lies on providing large scale dimensioning in broad band wireless system is a vital factor. so, an effective Path loss performance is a pivotal step requirement for deployment of wireless and cellular network planning in SIMO(Single-Input and Multiple-Output)model. In this work we are compared and analyze the various different propagation path loss models for our study. We computed the results by taking different receiver antennas heights(4m and 10m)in urban, suburban, rural (flat)areas. For measuring we have considered GSM(940 MHz) and WIMAX(3.5 GHz)in urban, suburban(NLOS) condition for rural(LOS)condition and used MAT Lab simulator for generating results.

To fulfill the end-users demand for access to the Internet “anywhere-anytime” and ensure quality of service, is the WiMAX (Worldwide Interoperability for Microwave Access) technology standardized based on IEEE 802.16 that provides efficient packet radio interface enabling transmission of high data rates. WiMAX network became popular and receives growing acceptance as a Broadband Wireless Access (BWA) system which is the solution of “last mile” wireless broadband. WiMAX has potential success and is gaining hike all over the world for deployment of the network in its line-of-sight (LOS) and non-line-of-sight (NLOS) conditions for both fixed operation below 11GHz and Mobile operation below 6 GHz frequency range. In the first step of cell planning and deployment of wireless network, estimation of path loss is very important in turn to get better signal strength to access Internet. In this work, we have used well-structured propagation models for analysis and comparison at different terrain areas, the models are - COST231 Hata model, COST231 Walfisch-Ikegami model, ECC-33 model, Ericsson model, and SUI model for SIMO (Single-input Multiple-output) channels. Using environmental parameters and some correction factors path loss is calculated for all terrain (urban, suburban, and rural) conditions. This provides guidelines for cell planning of mobile WiMAX at cellular frequency between 2-6 GHz.

Technology keeps evolving every second. Humans receive all the essential information with just one touch. Be it the weather forecast or ordering any grocery or communicating with one's peers, everything happens so easily and efficiently. It is undoubtedly user friendly. When the same technology associates itself with the medical equipment it becomes easier to fetch and process the patient's data in real time. It also helps to make several life-saving, spontaneous decisions for the critical care. This paper talks about the patient monitoring system. The physiological parameters of the patient are continuously monitored in real time using sensors. The data that is obtained from the sensor is then sent to an Arduino Uno microcontroller where it is analyzed. If the patient's data differs from the required threshold values, an emergency message is sent to the assigned doctor's mobile. This is done using the GSM module which is interfaced with the microcontroller. Verifying the system in software is done using Proteus.
