QoS Aware Routing Scheme Based on Traffic Priority for Wireless Sensor Networks

Wireless sensor networks (WSN) have generated tremendous interest among researchers these years because of their potential usage in a wide variety of applications. The most predicament issue that happens in WSN is Congestion. Congestion causes packet loss, which in turn reduces throughput and energy efficiency. Therefore congestion in WSNâs needs to be controlled for high energy-efficiency, to prolong system lifetime, improve fairness, and improve quality of service (QoS) in terms of throughput (or link utilization) and packet loss ratio along with the packet delay. This paper proposes a new protocol for data delivery into high congested areas. Proposed algorithm provides an efficient way to overcome congestion in wireless cluster sensor network. Proposed algorithm provides priority both on data and location.
