Wireless Sensor networks play an important role in the safety and security of industrial zones, forests etc. These networks are being used on a large scale for monitoring various environment conditions and also for agriculture across the globe. In India, from a past few years these networks are being used for Landslide Detection and monitoring. Wireless sensor Networks face a challenge of overcoming their short lifetime due to the usage of batteries in the sensor nodes. The energy Consumption in the sensor nodes is maximum during routing of the data.The proposed algorithm aims at reducing this power consumption and improving routing of WSNs using the concept of fuzzy logic and A-star algorithm. Thus the proposed algorithm is combination of networking with artificial intelligence. The proposed algorithm uses mainly three factors minimum hop distance, remaining power of a node and minimum traffic load to make the routing decision. The performance of this algorithm is effective and could increase the overall life-time of an WSN by nearly 20-25%.
