Abstract: wireless sensor networks is a growing class of highly dynamic, complex network environment on top of which a wide range of applications, such as habitat monitoring, object tracking, precision agriculture, building monitoring and military systems are built. The real time applications often generate urgent data and one-time event notifications that need to be communicated reliably. The successful delivery of such information has a direct effect on the overall performance of the system. Reliable communication is important for sensor networks. Urgent data transmission has been a serious problem for Wireless sensor networks. WSN face difficulties in handling urgent data like congestion and reliability due to their unique requirements and constraints. Various protocols for congestion avoidance and reliability achievement for WSN have been proposed recently. Few of them have also worked on congestion elimination. These protocols try to minimize the problem using different mechanism. This paper explores these mechanisms and tries to find their features and limitations which directed us for our research.
