Sensor networks are dense wireless networks of tiny, low-cost sensors, which collect and sense parameter. Wireless sensor networks facilitate monitoring and controlling of physical environments from remote locations with better accuracy. WSN is having applications in a variety of fields such as environ-mental monitoring; military purposes and gathering sensing information in inhospitable locations. Fault recovery and Network management for Wireless Sensor Network Infrastructure is a challenging area where the management operation is to run on minimal or zero cost. The network data packets routing costs more, hence managing this unstructured network improves the network efficiency and extend the network lifetime. The deployed sensor nodes have a fixed battery life and there are some attempts made to manage this WSN network efficiently to improve the lifetime. In this paper, we focus on different networking parameters and proposed a technique that can be used efficiently for fault recovery and management.

"Egocentric spatial language uses coordinates in relation to our body to talk about small-scale space ('put the knife on the right of the plate and the fork on the left'), while geocentric spatial language uses geographic coordinates ('put the knife to the east, and the fork to the west'). How do children learn to use geocentric language? And why do geocentric spatial references sound strange in English when they are standard practice in other languages? This book studies child development in Bali, India, Nepal, and Switzerland and explores how children learn to use a geocentric frame both when speaking and performing non-verbal cognitive tasks (such as remembering locations and directions). The authors examine how these skills develop with age, look at the socio-cultural contexts in which the learning takes place, and explore the ecological, cultural, social, and linguistic conditions that favour the use of a geocentric frame of reference"--
