Wireless sensor networks (WSN's) have become the part and parcel of our life. The Wireless sensor networks are used to sense and process data in applications like Water Level Monitoring, Vehicle Tracking and Patient Health care Monitoring systems. The energy is supplied to the sensor node through the battery. As the battery storage cannot be retained for longer time, the sample of information may not be collected continuously and send to the Base Station with a regular interval of time. The collection of information and its processing will be difficult, as there would be dynamic change in topology due to failure of existing nodes, addition of new nodes, link failure, change in parameters and the amount of battery storage capacity left in nodes. The Sensor nodes must observe the context, identify the dynamic changes and adapt to the new operating conditions. The challenges to be addressed during the establishment of an infrastructure-based reconfigurable Wireless Sensor Networks are Localization, Software Development, Role Assignment, Design of Code Dissemination Algorithms, Routing, Reconfiguration Model, Configuration Management and Security. Many Frameworks have been proposed to establish an infrastructure-based Wireless Sensor networks. But, there exist a need for an adaptive infrastructure-based reconfigurable framework which has to reconfigure at the runtime. |
