Wireless Sensor Networks have limited resources with traditional data gathering techniques. One of the limitations of wireless sensor nodes is its inherent limited energy resource. Therefore, designing an effective wireless sensor network to maximizing the lifetime of sensor node in order to minimize maintenance and maximize overall system performance becomes important. In this paper, the authors have outlined the design factors and challenges in sensor networks. Then, they describe several MAC layer and routing layer protocols proposed for sensor networks. In this paper, they propose an adaptive approach to find an optimal routing path from source to sink when the sensor nodes are deployed randomly deployed in a restricted service area with single sink.
