Wireless sensor network consists of inexpensive sensing devices with limited resources. In most cases, sensors are not equipped with GPS-like receiver due to its cost. And GPS units do not function well in environmental difficulties. The Knowledge about geographic position of sensors is critical in many tasks such as event detection, network management and routing. This forces to develop an accurate, efficient and fast localization technique. Traditional localization techniques like relative localization require an arbitrarily long period of time. Time is an essential factor in the localization of sensors in wireless network. The efficiency of location based applications depends on the time taken to determine the position of sensors in the network. In the case of industrial and military applications where human participation is impossible, sensors play a big role. The first step of these applications is to determine the position of sensors in the network. The time taken to locate the sensors should be minimum so that location based applications can be started as soon as possible. Traditional method of localization requires first finding the position of the nodes in their own local coordinate systems and finally converting it into global coordinate system. It increases the number of rounds of communication. Thereby it increases the time to locate the sensors. We present a new protocol TBEL for localization of sensors in WSN & MANET within a given time bound by using 2 hop technology and the results are analyzed using simulation studies
