Key generation and key authentication provide a security facility for storage a data over cloud network. The data storage over cloud network process involved multiple servers and required multiple key authentication process. The multiple key authentication process degraded the performance of cloud network. And the process of key generation and key authentication take more time ...

Wireless sensor nodes are inherent limited energy resource. Besides maximizing the lifetime of the sensor node, it is preferable to distribute the energy dissipated throughout the wireless sensor network in order to minimize maintenance and maximize overall system performance. Any communication protocol that involves synchronization of peer nodes incurs some overhead for setting up the ...

An ad-hoc network could be a multiple-node wireless network wherever all nodes are integrated to keep up network connectivity without a centralized infrastructure. In Mobile Ad-hoc wireless NETwork (MANET), secure communication is more difficult job because of its distinctive options like infrastructure less, wireless link, distributed cooperation, dynamic topology, and lack of association, resource affected ...

Cooperative communication means wireless nodes can help each other for communication. In this paper, study of cooperative wireless communication is done and proposes a cooperative system with different relay selection modes for the better error rate performance of the cooperative communication system. The cooperative relay network is the integrated part of the long distance communication ...

Wireless sensor networks tranquil from a large number of sensor nodes with the ability to sense and process data in the physical world in a timely manner. The sensor nodes contain a battery constraint which limit the network lifetime. Due to energy constraints, the deployment of WSNs (Wireless Sensor Networks) will required advance techniques to ...

Contemporary advances in wireless sensor networks have resulted in many new protocols specifically designed for sensor networks where power awareness is most important consideration. Most of the attentiveness, however, has been given to the routing protocols on the grounds that they would differ depending on the applying and network structure. This paper surveys latest routing ...
