Analysis of Congestion Control Mechanism for IOT

In IoT (Internet of Things) network, a big amount of data is generated within a period of time. Hence it is required to critically consider and design a load balancing protocol. In this paper we survey different congestion control mechanisms designed for IoT based network, classified in two major categories i.e. protocol dependent and performing offloading. These classifications are based on technique used to balance load and avoid congestion respectively. Protocol dependent approach is further classified as application layer protocol (CoAP) or network layer (RPL) protocol. These techniques improvise CoAP and RPL protocols to handle congestion issues. Offloading dependent approach covers different methods to balance the load evenly within a network. This analysis also includes the major concerns and the focus of different techniques to achieve congestion control within an IoT network.
