Nowadays Wireless sensor network achieve much attention due to its several real time applications like in military works, fire detection, temperature sensing etc. Sensor nodes are randomly distributed in the network and have limited energy. Due to this energy constraint, efficient routing protocol comes into picture. A sensor node senses the environment and generated the data. It sends the data to...
Wireless sensor network (WSN) is a network which includes spatially distributed autonomous devices using sensors to monitor environmental or physical conditions. WSN is emerging as popular and essential ways of providing pervasive computing environments for numerous applications. The sensor nodes are constrained in terms of energy and therefore energy consumption and extending network lifetime is...
WSN consists of small sensor nodes with a set of processor and limited amount of inbuilt memory units for purpose of sensing various types of relevant data from any specific region of environment. Some important applications of WSN are military, machine surveillance, preventive maintenance, disaster relief operations etc. In this type of network, routing is a little bit more complex as compared to...
Disasters are inevitable aspects of the human civilization and the limitation of extending the medical infrastructure to every corner of the demography is a challenging task. Technology can cater to need of the availability of medical expertise for each affected individual in the disaster virtually. A medical infrastructure can be envisioned using existing LAN and WAN communication technology standards...
Due to wide need of wireless sensor networks in environmental monitoring, medical, military, and agriculture, to keep these networks secure and authenticated is very important. Certificateless cryptography is an efficient approach studied widely because it eliminates the need of certificate authority in public key infrastructure. There are no. of security algorithms based on PKC (Public Key Cryptography),...
Today WSNs having different important role in different fields. Generally WSNs consist of thousands of small, cost effective, constrains on memory and processing capabilities to sense data periodically from predefined region. Wireless sensor network deployed in war like area or area in which after deployment of wireless sensor network any change is not possible. So, energy consumption is one of the...
Wireless sensor networks (WSNs) have many applications in military services, health centers, industries as well as home surveillances. In such networks energy efficiency of nodes and life time of network are main concerns. Different clustering approaches are used to efficiently optimize the energy of sensor nodes. Clustering also improves the scalability of sensor nodes. We reviewed different approaches...
In this modern era of technology wireless sensor networks have broad area of applications. Various applications of sensor network needs the communication to be authenticated and secured. Researchers have developed many schemes for intruder detection in WSNs, but those schemes are very complicated and require complex encryption and decryption process for intruder detection. In this paper we proposed...
Mobile ad hoc networks (MANETs) provide a wide range of applications such as disaster relief, military application, wireless sensor network (WSN), education, entrainment, health, commercial and civilian environments. One of its important applications is in commercial and civilian environments that cover e-commerce, vehicular services and networks of visitors at airports. Nowadays, phishing attacks...
Today wireless sensor Networks (WSNs) has important role in various fields. Sensor networks contain many sensor nodes for the purpose of sensing the data from the environment of a particular region. The major design issue in this area is to optimize energy efficiency of a sensor node as the power source of sensor node is limited and also it is not feasible to replace or recharge the power source of...
Mobile Ad hoc Networks (MANETs) are the networks of mobile nodes which do not require any access points to communicate with each other within the radio range. Due to their applications in situations such as emergencies, crisis management, military and healthcare, message security is of paramount importance in mobile ad-hoc networks. The paper proceeds with a brief introduction of MANETs followed by...
Wireless sensor networks (WSNs) are appealing to researchers due to their wide range of application potential in areas such as target detection and tracking, environmental monitoring, industrial process monitoring, and tactical systems. As medium access control (MAC) has a significant effect on the energy consumption, energy efficiency is one of the fundamental research themes in the design of MAC...
