Congestion occurs if more number of sources sends a lot amount of information for some system for handling. The congestion in a sensor system which is far away can lead to loss of packets and long delay. Each application has different qualities and requirements like transfer speed, rate, delay and packet misfortunate. Different kinds of information in a heterogeneous sensor network system can have different requirements. The parent sensor node (or hub) assigns the transmission speed according to the requirements of child nodes. Congestion is calculated in terms of packet service proportion (or ratio) and congestion notification is understood. The standard through put gets appeared in the outcome. © 2016, International Journal of Pharmacy and Technology. All rights reserved.
