Abstract: Wireless Sensor Networks (WSNs) have emerged as an important new area in wireless technology. In many real-life environment applications of WSN’s, data is generated continuously and it should reach the sink node without delay and loss. Congestion is the one of the main problem in Wireless sensor networks. Congestion detection and Avoidance in WSN’s is a critical issue, it will not only affect transmission reliability, but also causes transmission delay and will waste valuable energy resources. The data flowing through the WSN have great impact on the link load. The way of handling the data against the congestion is tough task. Queue occupancy is an accurate indicator of congestion. In this paper we propose the scheme that detects efficiently congestion by using queue occupancy parameter of a node. If queue length of any node has reached maximum threshold level then data should not be transmitted through that node for certain time period to avoid congestion. It overcomes the congestion by selecting alternative neighboring node which does not cause congestion and transmit the data reliably and fastly to the destination (sink node) without delay and loss.
