Abstract
Wireless Sensor Network is one of the mechanisms to monitor different Wireless Sensor Network application such as environmental and habitat monitoring. In which cooperatively pass their data through the network to a main location or sink where the data can be observed and analysed.
Sensor placement is an important task in WSN applications. The number of sensors and their location will affect the performance, accuracy, and cost of the deployment. One of the important issues in WSNs application is node deployment which decides where the sensor nodes should be placed in order to satisfy the desired requirements like maximize the efficient coverage area ratio and minimize the size of the network and cost. The effectiveness of these networks is determined to a large extent by the coverage provided by the sensor deployment scheme. Determining the required number of sensors to be deployed is a critical decision for wireless sensor networks
In this thesis we develop a homogenius sensor node deployment scheme using grid based deployment scheme where all of the sensor nodes have similar processing and hardware capabilities by placing node in Hexagonal scheme, which cover with minimum number of sensor node and reduces the cost of sensor node. The number of sensor node used evaluated by comparing with previous system in which the proposed work used minimum number of sensor node for covering the region than from previous one. The proposed system consider the shape of the monitored land and we integrate PEGASSIS, hierarchical clustering routing protocol, where each sensor node transfer data to neighbourhood node. We used MATLAB for implementation of the proposed system and performance evaluation. From the evaluation result, the proposed homogenius node deployment approach has a minimum number of node, cost effective and better coverage than the existing shape based node deployment approach.
