A Wireless sensor network (WSN) has important applications such as remote ecological monitoring and target tracking. This has been enabled by the availability, particularly in recent years, of sensors that are smaller in size and smart. These sensors are equipped with wireless interfaces with which they can communicate with one another to form a network.(More)
The IEEE focuses on the physical and MAC layer of Wireless Sensor Networks (WSN) and the Internet Engineering Task Force (IETF) works on Network layer and higher in the seven layer OSI reference model for networking. The IEEE 802. 15. 4 standard, defines the physical layer (PHY) and medium access control (MAC) sub layer specifications for low-data-rate(More)
Wireless sensor networks consist of sensor nodes with sensing and communication capabilities. As sensor nodes are generally battery-powered devices, the critical aspects to face concern how to reduce the energy consumption of nodes, so that the network life time can be increased to reasonable times. The efficiency of space-time block code-encoded (STBC)(More)
In this paper data compression is becoming more popular, because it helps to reduce the size.A number of clustering protocols have been explored in order to obtain the effective energy usage in WSNs. It is based on randomized rotation of the CHs to distribute the energy load among the sensor nodes evenly in the entire network. Each node elects itself as a(More)
To increase the life span of wireless sensor network, energy consumption must be minimized while satisfying given throughput and delay requirement. In this paper, we described an energy model based on cooperative MIMO scheme considering of both transmission and data aggregation energy is proposed for wireless sensor network. Based on this consequence,(More)
Precision agriculture is a process in which information and technology is used for collection of high resolution spatio-temporal data regarding atmospheric and soil conditions from farm land. With the help of farm land data and an appropriate crop-growth model, a decision support system regulates the agricultural needs precisely in order to gain maximum(More)
An energy-efficient communication schemes in wireless sensor networks (WSN) is highly desirable where energy consumption is constrained. In this paper, the mathematical model of energy consumption per bit in wireless sensor network using Cooperative MIMO is presented. Cooperative MIMO transmission and reception can simultaneously achieve the energy savings(More)
