Review of different deployment schemes in wireless sensor networks

Abstract

In recent years, extensive research is going on in each and every domain of wireless sensor network. Researchers' main focus is on issues like connectivity in network, network life time, and energy efficiency, secured and reliable communication among nodes. Sometimes wireless sensors are used to sense parameters from hostile environment where user involvement is very less or not at all. In such conditions, it's difficult to deploy and configure sensors manually. So numerous numbers of automated schemes are invented to deploy sensors in hostile environments so as to cover maximum area, improve nodes lifetime, efficient communication and connectivity by deploying nodes at proper places. Secure and efficient deployment schemes are one of the major challenge in the field of wireless sensor network.
