Wireless Sensor Networks represents a new pattern for extracting the data from the environment for many agricultural, industrial and scientific applications. Data gathering protocols are formulated for configuring the network and collecting the information from the desired environment. Sensors have limited battery power and the communication module consumes(More)
225 Abstract— In Wireless Sensor Networks (WSN), nodes around the sink would deplete their energy faster, leading to what is called as energy hole around the sink. Multi-hop relaying is the main reason for the energy hole problem which can be avoided by sink repositioning technique. Although sink deployment can provide optimal solution, they are not always(More)
An integral aspect for designing any efficient wireless sensor network is the conservation of energy and the optimization of the power consumption. Continuous and prolonged availability of power plays a vital role in keeping the sensors energized. The power required by the sensors is largely dependent on their batteries which may require regular recharging(More)
Sink relocation is essential in wireless sensor network since relocating sink can balance the traffic load in the midst of multiple nodes and thereby decrease the miss rate of real-time packets. The main constraint in wireless sensor networks is limited energy supply at the sensor nodes so it is important to deploy the sink at a position with respect to the(More)
Wireless Sensor nodes carry limited generally irreplaceable power sources. One of the major problems while handling the wireless sensor network is the limited availability of the power for the sensor nodes. Due to this energy constrain the data needs to be managed wisely in order to extend the lifetime of the network. In many scenarios sensor nodes will(More)
Wireless Sensor Networks comprises of large number of sensors which are deployed in the network. These sensors are battery operated devices and energy constraint is the main problem that needs to be addressed effectively and efficiently. In order to overcome the problems that arise due to energy hole and multi hop transmission a Hybrid model of Sink(More)
In today’s wireless Sensor Networks, the location information of the various sensors that are deployed in the network is the basic requirement. Localization plays a very vital and challenging role where it becomes very important to find the location of the various sensors with respect to the geographical extent of the entire network. Here we have proposed a(More)
The location information is very important in many wireless sensor network applications where in from which node the data is generated needs to be determined. Therefore it becomes necessary to know the location of each and every sensor that is deployed in the network. In our proposed Localization technique we have deployed static sensors in the geographical(More)
