Prioritized Congestion for Detection and Avoidance by Tadr Algorithm Toalemorite Throughput in Wireless Sensor Networks

Abstract

Wireless sensor network is a rising technology that provides the various applications in defense and industries. Congestion and security are the main parameters in sensor networks. Congestion takes place when several nodes can transmit packets to a single channel. When nodes get closer to the sink, the traffic arises, which leads to congestion. It leads to loss of information, heavy packet loss, packet delay and less energy efficiency. A congestion control scheme is necessary to improve the quality of service (QoS) and system lifetime. The modified LACAS is to avoid traffic from many to one node. This is mainly designed for health care units. The nodes interact with the previous nodes at continuous intervals of time to reduce the congestion. Here, TADR algorithm with buffer management is implemented with MAC layer and transport layer. A TADR algorithm is designed to route packets around the blocking regions and spread out the unnecessary packets in different paths of idle nodes and low weighted nodes. The buffer automatically adapts the sensor’s forwarding rates to be nearly optimal without causing congestion. The simulation result shows that the throughput gets increased, and packet loss is reduced drastically.
