“…The major congestion control methods are categorized into traffic control protocols and resource control protocols [19]. Congestion are handled by conventional methods like network resource management and traffic control [20] and also by soft computing methodologies like feed forward neural networks [21]. A distributed congestion control mechanism using adaptive traffic mechanism to provide fair packet delivery is discussed by Daniela et.al [22].…”

Collective nodes are organized to form cooperative networks. In order to access the network resources, various protocols were introduced for portable devices. In HWSN, the sensor nodes are scattered, and the position of the nodes are altruistic. Hence, the main challenges in HWSN are topology control, battery optimization, packet loss and link lifetime. The existing techniques do not concentrate on all these issues at the same time. The objective of this work is to provide congestion-free data transfer with higher throughput, decreased packet drop ratio and minimum transmission delay. In the proposed methodology, three protocols are designed and developed, namely, Hop by Hop Rate Adjustment Protocol (HHRA), Energy Efficient Data Transfer Protocol (EEDT) and Alternative Routing Congestion Control Protocol (ARCC). The HHRA protocol senses the traffic in the channel and adjusts the transmission rate accordingly which controls the flow of data to avoid congestion. Secondly, the EEDT protocol is used to find specific nodes that are more efficient between the source to the sink and transfer data packets through those nodes which reduce the hop counts to minimize transmission delay. Thirdly, the ARCC protocol is used to redirect the path of transmission during the occurrence of congestion. Thus, the proposed work ensures congestion free transmission with the higher quality of service and minimum transmission delay.</p><p> </p></td></tr></tbody></table>
