Abstract
The advances in recent technology have lead to the development of wireless sensor nodes forming a wireless network, which over the years is used from military application to industry, household, medical etc. The deployment pattern of sensor nodes in Wireless Sensor Network (WSN) is always random for most of the applications. Such technique will lead to ineffective utilization of the network; for example fewer nodes are located at far distance and dense nodes are located at some reason and part of the region may be without the surveillance of any node, where the networks do consume additional energy or even may not transfer the data. The proposed work is intended to develop the optimized network by effective placement of nodes in circular and grid pattern, which we call as uniformity of nodes to be compared with random placement of nodes. Each of the nodes is in optimized positions at uniform distance with neighbors, followed by running a energy efficient routing algorithm that saves an additional energy further to provide connectivity management by connecting all the nodes. Simulation results are compared with the random placement of nodes, the residual energy of a network, lifetime of a network, energy consumption of a network shows a definite improvement for uniform network as that of with the random network.
Highlights
Wireless Sensor Network (WSN) is developed for small scale level applications that use the sensors for communication
For example in a military application, it is difficult to reach the specified areas so as to practically place the sensors, in that case sensors are randomly thrown from an area above the ground; another case would be the scenario of an agricultural application which requires structured monitoring, where sensors are uniformly distributed to receive the data at regular intervals
The proposed work is intended to concentrate on the different placement of nodes like random, circular and grid based scenario of a network that is mainly worked out to save the energy consumed by the network on par with sensor nodes and to increase the network lifetime
Summary
WSN is developed for small scale level applications that use the sensors for communication. WSN can establish the network on its own, which usually consists of low cost, low power, low energy features, where the data transfer through these is done efficiently by various techniques in order to increase the network lifetime. It is always referred by most of the researchers that WSN uses maximum communication energy for communication, which intently can be considered as, sensor node can be made to use minimum energy to reach the neighbors trying to save the energy consumed. The proposed work is intended to concentrate on the different placement of nodes like random, circular and grid based scenario of a network that is mainly worked out to save the energy consumed by the network on par with sensor nodes and to increase the network lifetime
