Optimal Relay Node Placement to Improve Expected Life Time in Wireless Sensor Network Design

EasyChair Preprint 3175

Abstract

Wireless sensor network has become one of the main emerging technologies today in the world to enhance performance and scalability of the real-time monitoring designs. Functionality of wireless sensor networks differ from one application to another.  Deployment of relay nodes is necessary to forward the sensed data from the sensor node to the sink node. Placement of relay nodes has becom one of the major issues in WSN. This paper proposes an algorithm which is capable of enhancing the expected lifetime of a wireless sensor network by placing relay nodes in optimum locations. The sensors are operated under extreme power constraints. However, we use two tired network architecture to reduce power consumption in the network. Here, COOJA network simulator is used  to simulate the proposed algorithm. And therefore, network lifetime is measured and observed.
