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...
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...
