In this paper, an efficient routing protocol for patient monitoring system in rural areas was proposed using wireless sensor network (WSN) so that the patients can be treated within less time. In this system, a village with GSM network is considered and the people in that village are continuously monitored using AMON sensor, an advanced medical monitoring and alert system. All the AMON's work in ADHOC...
In recent past, researchers have shown a lot of interest in Under Water Sensor Networks (UWSNs) because of its application in wide range of domains. UWSN, actually a sub body of Wireless Sensor Networks (WSN), facilitate with radio communication with high-precision of information to a sink node from any of the source node. The Role of any-casting is of significant importance in the context of routing...
In nigh application, it is indispensable to discover or supervise the behavior of the surrounding situation at a fine resolution over large spatial-temporal scales therefore WSN (Wireless Sensor Network) is well-advised. Because of smaller size and low power requirement of sensor device use of WSN for watching the surrounding action is increased time to time. Numeral of sensor inside WSN is proportionate...
Monitoring ports, harbors and oceanic territories is gaining huge interest especially to combat military crisis, smuggling and terrorist activities. Underwater Wireless Sensor Network can be a viable solution for tracking objects like trespassing ships approaching a harbor and monitoring the activities on the ocean surfaces. In this paper we have proposed a new paradigm for underwater tracking mechanism.
The widespread deployment of wireless sensor networks (WSNs) in diverse types of applications motivated the development of strong security measures to protect these networks. The main challenge against deploying strong security algorithms is that WSNs suffer from major constraints in terms of power and computing resources. WSNs impose a primary condition on the design stage that requires any protocol...
In the operation of industrial monitoring in distributed manner, new approaches have emerged to achieve the objective of efficient data exchange. Wireless sensor network has up came as an optimal solution to distributed monitoring. In the approach to precise monitoring and remote controlling, new approaches of resource controlling and operational controlling were developed. However, the node level...
Wireless sensor networks (WSNs) are susceptible to most security attacks. There are some limitations such as reliability, energy efficiency, and scalability, which affect sensor nodes. These limitations mostly affect the security of wireless networks. Also, limited capacity of sensor nodes accounts for the security attacks on WSNs. Applications such as military surveillance, traffic surveillance,...
In Wireless Sensor Networks (WSN), Quality of Service (QOS) plays a significant role as networks performance is dependent on QoS only. WSN is very popular because of its wide application range. WSN has limited resources such as computational power and energy constraint. Congestion is one important subject which has drawn attention of many researchers. Congestion results into reduced throughput and...
Indoor Air Quality (IAQ) is an urgent topic nowadays. It is concluded that 90% of human's life is spent indoor. However, it is commonly known that materials used in construction or furniture is often detected to release Volatile organic compounds (VOC) which affect IAQ significantly and lead to dizziness, respiratory irritation, fatigue, asthma and allergic airway disease and even cancer. As a result,...
A distributed and collaborative nature of wireless sensor network cause many challenges to provide security in network. Most of the outsider's attacks are prevented by encryption and authentication technology, but to control insider attacks are difficult. A malicious sensor node causes lot of packet losses, energy wastage and increase in time to reach final destination. In this paper, Enhanced Beta...
The wireless sensor network (WSN) consist of wireless sensor nodes, which are deployed randomly in a surge of unforeseen applications. Topology Control (TC) is the most essential approach used for minimizing energy consumption that extends the in WSN time. Also increases the throughput of the topology and minimize the radio interference. The aim of the proposed context aware topology control is to...
Sensor enabled health care monitoring system is the most demanding technologies of health care sector. It is in high demand to monitor individuals. It becomes necessary in society as the number of patients in clinics and hospitals are continuously growing. This on-demand monitoring is being facilitated by the wireless sensor networks (WSN). This monitoring is done both at the patient's home and in...
Wireless Sensor Communication Networks have more concern on its routing techniques. Since the WSCNs nodes are battery powered, routing algorithms should assure the concept of energy saving without affecting the other performance metric like Throughput, Delay and Packet delivery ratio etc. The modified AOMDV called as Enhanced Energy Efficient Multipath Routing Protocol ( EEEMRP )is a proposed algorithm...
Problem of Congestion in Wireless Sensor Network (WSN) is an area which draws attention of various researchers in recent years. The challenge lies in developing a model for routing which can find the optimized route on the basis of distance between source and destination and the residual energy of the node. Various models have been proposed and developed from time to time and their merits and demerits...
A new combination between Wireless Sensor Network (WSN), mobile robot and satellite technology for Indonesian volcano monitoring system, Mobile Monitoring System for Indonesian Volcano (MONICA) has been developed.
