A vast amount of literature and research work exists on Wireless Sensor Networks and the issues concerning them. In this paper, we have conducted an exploratory study on the sensor networks to begin with and the various issues and challenges faced in setting up and maintaining sensor networks....

Energy evaluation and planning are important in industry for overall energy savings. Traditionally these functions are realized in wired systems formed by communication cables and various types of sensors. However,the installation and maintenance of these cables and sensors is usually much more...

Energy efficient protocol design is the aim of current researches in the area of sensor networks where limited power resources impose energy conservation considerations. In this paper we concern for Medium Access Control (MAC) protocols the recent technology that is used in the Wireless sensor...

Key Management is a critical security service in wireless sensor networks (WSNs). It is an essential cryptographic primitive upon which other security primitives are built. The most critical security requirements in WSNs include authentication and confidentiality. These security requirements can...

Continuous monitoring of production of yarn is an important process requirement for good productivity in a ring frame machine in textile industry. So, collecting the data on yarn breakages using an appropriate Wireless Sensor Network (WSN) has been taken as a research problem in this work. The...

The issue of energy saving is significant since in a battery-operated wireless node, the battery energy is finite and a node can only transmit a finite number of bits. To extend the life span of a node in wireless sensor networks, an energy-efficient communication technique is mandatory so that...

The sensor nodes in wireless sensor network are deployed to function in faraway locations. On the basis of network setup WSN can be: Flat, Hierarchical or cluster based network. The diverse benefits of cluster based networks are efficient utilization of energy, improved data communication,...

The amount of water evaporated from the soil surface and lost through transpiration of the crop is collectively called evapotranspiration. With drip irrigation, evaporation from the soil is minimized, particularly in plastic mulch production systems, leaving crop transpiration as the main...

As the cell and PCS world collides into wireless LANs and Internet-based parcel information, new networking approaches will maintain the blend of voice and information on the composite establishment of cell base stations and Ethernet-based wireless passages. Cross-Layer Design has become an...
