An Improved Soft Computing based Congestion Control in Routing the Data in Wireless Sensor Network

The congestion control is defined as a contrivance that is used to control and monitor the entry of data packets into the network. This helps to enhance and develop a better infrastructure in the communication network. The wireless sensor network is a communication network with infrastructure that are accompanied with less wireless network that is composed of innumerable nodes that are transportable through several instructions in the system. The nodes are interconnected in the communication system with each other in random fashion. The congestion is denoted as a decrease in the quality of service (QOS) in network that results in packet loss and new connections in the network may get blocked. The congestion can be prevented by implementing open loop congestion control policies. This can be controlled by the source or through the destination. This happens when there is a shortage in the buffer space. The soft computing based congestion control in routing the data is done through the following techniques that are classified as fuzzy logic system, artificial neural network, game theory based and particle swarm optimization techniques.
