There are challenging situations occur in field of mines due to changes in environmental conditions & abrupt events. A design of a wireless sensor network contains ZigBee protocol & a Structure-Aware Self-Adaptive WSN system. There are two types of node architecture which is Master & Slave node architecture i.e. moving & fixed node respectively. For safety & prevention from accidents the proposed system uses Wearable Sensor System (WSS) i.e. moving node.WSS is a life guard system which is used to monitor environmental and physiological parameters in dangerous environment. Here proposed system uses routing protocol for fast data transmission. For prediction of different conditions uses Bayesian Algorithm and gives probability based decision making.

Introduction Environment monitoring in industries, mines is an important application of wireless sensor network (WSN) that has commercial potential. Due to changes in environmental conditions there are challenging situations occur in field of mines. For example gases level increases, leakage of hazardous gases, abrupt event occurs suddenly. So this paper contains design of Wireless sensor network (WSN) to monitor & control environment condition in mines [1]. WSN contains distributed autonomous sensors which are self adaptive network system. WSN is built of number of nodes which are connected through wireless medium. WSN contains distributed autonomous sensors which are self adaptive network system. WSN is built of number of nodes which are connected through wireless medium. A low power and cost effective Wireless Sensor Network is developed for monitoring of environment & automation by using ZigBee/IEEE 802.15.4 protocol [3] which is a global standard protocol used for WSN. The main objective of this paper is to predict the conditions in mines & prevent from accidents. In underground mines, there is harsh thermal environment present & sometimes gases leaks in environment above their decided threshold value. These conditions are dangerous for life & hazardous for health so for prevention from such conditions this paper contains Wearable Sensor System (WSS) [4]. Wearable Sensor System is a life guard system. WSS contains on body sensor network system which is used to monitor environmental and physiological parameters in dangerous environment. WSS is introduced as master node i.e. moving node in this paper because it is portable sensor system. The basic communication scenario of nodes is shown in Fig. 1.The stable node & moving node are present in underground mines in same network. The stable node is having different types of sensors to monitor environment under mines. Stable node i.e. slave node collects all environmental information & forward it to the remote server & Moving node. After result analysis at the remote server, it makes probability based decision & gives all information to the moving node. Due to this, moving node predicts all conditions previously or before moving ahead Fig.1. Basic scenario of communication between nodes
