With the advancement of technology, the internet is changing and so is the development of things online. Buildings are going Intelligent and this trend is gaining momentum wireless network nerve play a major role in this concept. This concept works with one of the most widely used applications for wireless network sensor networks namely in the field of navigate. When an emergency arises, wireless network sensors detect danger and direct evacuees to distant places through physical contact with cyber. Emergency navigate is important to get rid of trapped users on the way out. Our focus is not only on directing users who provide a shorter way but also on a safer way. This helps to avoid congestion and leads to the use of alternatives that are often left unused which improves the survival rate of survivors. We suggest Intelligent Escape, a real-time, powerful, intelligent and easy-to-use exit system with a portable interface for emergency cases like fire. Unlike previous work, we examine changing conditions and calculate a personal way who escapes by looking at his features. Intelligent Escape, fast, cheap, multi-functional and mobile supported, collects a variety of natural sensory information and takes into account survivors' signals, using implants. The neural network (ANN) calculates the risk of personal use of each link on the site, eliminates that risk, and calculates the appropriate escape way under current conditions. After that, our program guides those who are excluded from the exit through statistics a way with voice and visual commands on a Intelligent phone. The consideration about the route coordination problem in emergency evacuation of large smart buildings is taken into account. The building evacuation time is crucial in saving lives in emergency situations caused by imminent natural or man-made threats and disasters. Conventional approaches to evacuation route coordination are static and predefined. Methodologies used are Ant Colony algorithm and Capture Wi-Fi signal in which the users equipped with mobile phones or PDA’s interact with the sensors through Wi-Fi. GPS is inadequate for indoor location positioning. Wi-Fi is a technique used for location tracking with wireless access points(AP’s).On occurrence of hazardous accidents like fire or gas leakage, sensor value set goes beyond threshold and emergency is triggered. The centralized control/sever has the location details of the building (for path navigation and also mapping details to exit).
