Given the sensitivity of the potential WSN applications and because of resource limitations, key management emerges as a challenging issue for WSNs. One of the main concerns when designing a key management scheme is the network scalability. Indeed, the protocol should support a large number of nodes to enable a large scale deployment of the network. In this(More)
The main requirements of wireless sensor network are to prolong the network lifetime and energy efficiency. In this paper, Heterogeneous-Hybrid Energy Efficient Distributed Protocol (H-HEED) for Wireless Sensor Network has been proposed to prolong the network lifetime. In this paper the impact of heterogeneity in terms of node energy in wireless sensor(More)
Research on wireless sensor networks has been studied and employed in many applications such as medical monitoring, automotive safety, and many more. Typically, sensor nodes have several issues such as limited battery life, short radio transmission range and small memory speed. However, the most severe constraint of the nodes is their limited battery energy(More)
Late leaf spot is a serious disease of peanut caused by the imperfect fungus, Phaeoisariopsis personata. Wild diploid species, Arachis diogoi. is reported to be highly resistant to this disease and asymptomatic. The objective of this study is to investigate the molecular responses of the wild peanut challenged with the late leaf spot pathogen using(More)
Peanut (Arachis hypogaea L) is one of the widely cultivated and leading oilseed crops of the world and its yields are greatly affected by various biotic and abiotic stresses. Arachis diogoi, a wild relative of peanut, is an important source of genes for resistance against various stresses that affect peanut. In our previous study a thaumatin-like protein(More)
Multiplication and square are elementary mathematical operations extremely important for core computing process. Also exponentiation, the process of raising a base number to a power is an important operation in many numerical computations. To keep pace with the technology, high speed applications require faster methods of multiplication and Square(More)
Preserving the consumed energy of each node for increasing the network lifetime is an important goal that must be considered when developing a routing protocol for wireless sensor networks. The main objective of cluster-based routing protocol is to efficiently maintain the energy consumption of sensor nodes by involving them in multi-hop communication(More)
In recent years, energy efficiency and data gathering is a major concern in many applications of Wireless Sensor Networks (WSNs). One of the important issues in WSNs is how to save the energy consumption for prolonging the network lifetime. For this purpose, many novel innovative techniques are required to improve the energy efficiency and lifetime of the(More)
