Object Recovery System Using Wireless Sensor Networks for Smart Cities

A smart city is an urban area provided with all the basic requirements like school, hospital, transportation, security etc. Different communication technologies are used to control and track different sectors of the smart cities, the Wireless Sensor Network (WSN) is one such communication technique. Here cluster-based network is used for tracking operation. While tracking, there may be a possibility of losing tracked object. Thus relocating the lost object becomes an important issue. In this work we propose to develop an object tracking system using WSN. The validation of the algorithm is done using the network simulator NS2.
