Certain investigations on congestion control algorithms in tcp based wireless sensor networks

Abstract

Wireless Sensor Network (WSN) is used globally in the most important essentials, which are used by most important data communication systems in many utility areas, including health care, military surveillance, etc. A large number of sensor nodes are used in a wide geographical area. Sensor nodes are used for various sensing applications, which send information to sink node. When data transmission takes place between the sensor nodes, and the nodes are close together with the nodes, then information is not lost. There are possibilities for congestion in the network, involving a high number of communication sensor nodes. Congestion is a big issue in the wireless sensor network, its performance degrades when node energy is very low in the network, and throughput becomes low. Overall network performance decreases by congestion issues, and the information sent is not fully reachable to sink node. Effective traffic congestion control is needed to deal with these problems. The congestion control system must act, to ensure notification of congestion, and to correct the traffic congestion. Wireless Sensor Network must guarantee to make the data communication successful, a configuration and its design is essential to avoid problems in the packets that cause packet loss and delays in the network. newlineOur research is taken in two different ways, first of all, find the congestion and prolong the scrolling algorithm on the network. There is another research, to detect congestion before its occurrence in WSN. newlineFlexible procedures are followed for avoiding unreasonable traffic between sensors, and staying on those nodes for a lifetime. This thesis proposes to avoid the congestion traffic in the network. newline newline
