This paper illustrates the successful application of fuzzy logic in wireless sensor networks. There are different disciplines which make use of fuzzy logic such as event forecasting, redundancy reduction, querying to sensor network database, deployment, clustering, MAC protocol etc. In this survey paper, clustering techniques with fuzzy logic are discussed which associates advantages of localized...
Wireless networks are increasingly used to serve real-time flows. We provide an overview of an emerging theory on real-time wireless communications and some of its main results. This theory is based on a model that jointly considers the delay bounds and throughput requirements of clients, as well as the unreliable and heterogeneous nature of wireless links. This model can be further extended in several...
Nowadays, Wireless sensor networks (WSNs) are appeared to be new and promising solutions for next generation real-time wireless monitoring applications. These WSNs could become a threat if suitable security is not considered before the deployment. However, if there is any loophole in security, that might opens the door to attackers and hence, endanger for the applications. So, user authentication...

The sensing technology combined with processing power and wireless communication makes it lucrative for being exploited in abundance in future. The inclusion of wireless communication technology also incurs various types of security threats. Although...
This paper presents the design of an adaptive HVAC based on psychrometric analysis and a De-Centralized control Algorithm for an Autonomous Wireless Sensor Network. The proposed system aims to initially differentiate the area under consideration into active and inactive zones and perform control operations on them. The De-Centralized control methodology follows a K:1 transmission protocol for optimized...
In this paper, we quantify the performance analysis of PingPong-128 keystream generator for wireless sensor networks. Although, PingPong-128 is not a standard stream cipher but still PingPong-128 keystream generator is an idea for resource constrained WSNs and can be widely used in the applications of secure communication, where the communication nodes have limited computation processing and storage...
Recent advancement in ubiquitous healthcare evolves to new challenges in ubiquitous communications. Secure communication in wireless sensor networks (WSNs) is one of the important issues, especially, when WSN comes to ubiquitous healthcare, where security is main requirement in sensor devices, communication and continuous real-time monitoring of patient in hospital or home network. WSN requires efficient...
In wireless sensor networks (WSNs); routing protocols are one of the main issues in existing research. These protocols make the best use of limited resources, particularly the energy efficiency and effectiveness of data dissemination. Few of them discuss security issues in homogenous sensor networks which consume much power, have poor performance limits and less scalability. In order to attain the...
With the advent of Wireless Sensor Networks (WSN's) covering a whole gamut of applications which is getting broader by the day and it is indeed necessary to study the nuances in WSN out of which aforementioned is one. WSN's consists of large number of deployed sensor nodes and a base node for aggregating data from deployed sensor nodes. Wireless Sensor Network's (WSN) are attribute based and they...
In this paper we are proposing a wireless sensor network based solution for typical indian city traffic. The objective is to understand and solve the congestion of the chaotic traffic. We are proposing to control and optimize the duration of time a signal is green, and the number of vehicles passing through the junction, in a given interval of time. Our objective is to use WSN to make the traffic...
Many Mobile Ad Hoc Network (MANET) routing protocols are exploited to work in a specific variety of Ad Hoc Networks like Wireless Sensor Networks (WSNs). This paper presents a performance evaluation of two MANET routing protocols B.A.T.M.A.N and OLSR. The implementation was achieved over a Real-World WSN considering some vital metrics like Packet Delivery Ratio (PDR) and Ratio Traffic Overhead (RTO)...
Digital homes are expected to be the standard in the near future when all aspects of the home can be monitored and controlled remotely by the home owner. For example, if the home owner is unsure whether she closed the garage door before leaving for work, she can view the status of the garage door on her portable computing device such as laptop, PDA or cell phone, and if the garage door is indeed open,...
This paper proposes AREA-MAC, a medium access control (MAC) protocol for wireless sensor networks (WSNs). AREA-MAC reduces latency and energy consumption of nodes by using low power listening (LPL) with short preamble messages. Other protocols like B-MAC use long preamble messages that cause higher latency, energy consumption, and control overhead on nodes. AREA-MAC provides a reasonable trade-off...
The recently standardized IEEE 802.15.4 protocol is emerging as a basic building block for wireless sensor network applications by providing many appealing features, such as low power, low cost, low data-rate, and simplicity. However, when treating applications with strict timeliness, energy, and bandwidth requirements several problems arise, triggering the need of a solution for an efficient twinning...
Wireless Sensor Networks (WSN) are planned to be deployed in critical applications like border surveillance, monitoring physical and chemical environmental phenomena, intelligent agriculture and personal healthcare. Theses days, researcherspsila vision is to implant sensor nodes in the human body, which will monitor the biological parameters and report them to the patient and the doctor, when abnormalities...
Sensor network applications such as environmental monitoring demand that the data collection process be carried out for the longest possible time. Our paper addresses this problem by presenting a routing scheme that ensures that the monitoring network remains connected and hence the live sensor nodes deliver data for a longer duration. We analyze the role of relay nodes (neighbours of the base-station)...
