A Novel Approach to Enhance TCP Throughput in Wireless Sensor Networks

Wireless sensor network consisting of a large number of distributed sensor nodes is widespread to controlling and monitoring environmental conditions and in recent years many applications in various fields of industrial, military, agricultural, and medical and other oil industry is allocated. Hence a lot of research is done to enhance their performance.

A sensor network has multi hop adhoc architecture. It means the source node couldtransmit to destination node by the aid of intermediary node. Each node can be either as a router to determine the path, or a (source/destination node.

Node movement is caused Routing algorithms be one of main challenging. This multi hop communication uses proactive routing algorithm like DSDV or reactive routing algorithm like AODV and DSR. Furthermore the resource limitation and havingerror prone wireless channel are their another main challenging. These problems cause decreasing the wireless sensor network performance. This paper addresses a modified version of TCP congestion avoidance mechanism to improve performance over error prone channels of sensor network.
