cluster base stations (cluster-heads) to evenly distribute the energy load among the sensors in the network. LEACH uses localized coordination to enable scalability and robustness for dynamic networks, and incorporates data fusion into the routing protocol to reduce the amount of information that must

Habitat and environmental monitoring is a driving application for wireless sensor networks. We present an analysis of data from a second generation sensor networks deployed during the summer and autumn of 2003. During a 4 month deployment, these networks, consisting of 150 devices, produced unique

In the paper, we devise and evaluate a fully decentralized, light-weight, dynamic clustering algorithm for target tracking. Instead of assuming the same role for all the sensors, we envision a hierarchical sensor network that is composed of (a) a static backbone of sparsely placed high

to send and receive data; also it depends upon distance between two nodes. Therefore with the help of Data aggregation technique we reduce the size of data. In wireless sensor network’s (WSN’s) nodes need less power for processing as compared to send data. Second technique is to reduce amount of energy

Recent research has provided means by which Wireless Sensor Networks (WSN) with dynamic deadlines can make use of mobile agents for data aggregation. Lot of research has already been done with respect to using mobile agents in case of static wireless sensor networks. This paper proposes, along

Wireless sensor networks (WSNs), are spatially distributed autonomous sensors used to monitor physical and environmental conditions, such as temperature, sound, pressure, etc. Each device can sense, process, and talk to its peers. All the sensor nodes are considered as little objects and therefore
