Description
Summary:Wireless Sensor Network consists of large number of sensor nodes distributed in an area. Due to the nature of upstream traffic, congestion more probably happens in the upstream direction. The congestion problem in WSNs is quite different from traditional networks. For efficient congestion control, an accurate and timely estimation of resource demands by measuring the network congestion level is necessary. To alleviate congestion, either the available resources have to be increased or the source transmission rate should be restricted. Most congestion control in WSNs has only focused on traffic control. The present paper proposes a resource aware congestion control which will prevent the congestion by increasing the path available resources. The proposed protocol adjusts the network resources based on the available energy capacity and node congestion level therefore it provides efficient power consumption, high packet delivery ratio in WSN.
