Study of Challenges in Sensor Node Deployment in Wireless Sensor Network

Abstract

Wireless Sensor Network is a network which consists of tiny sensors that senses required information from the sorrounding and passes it to the destination for further processing. Deployment of sensor node in wireless sensor network is the way of placing sensors in network for the collection of desired information from environment. Performance of a network in an application depends on the proper deployment of the sensor nodes. Particularly, when it is the case of heterogeneous sensor network, at most focus is required while deploying sensor nodes. Improper deployment reduces the efficiency of the network. It may not be always possible to deploy the sensor nodes easily .Particularly, in harsh environment, it is too difficult to deploy the nodes. In this paper we give a description of the different types of node deployment schemes and challenges developed so far for wireless sensor network.
