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 WSN's 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. The main focus of this paper is to provide modification in an existing system working with DSR (Dynamic Source Routing).This paper proposes modifications in the protocol of the existing system as AODV (Ad-Hoc On Demand Distance Vector). Proposed protocol provides an efficient way to overcome congestion in wireless cluster sensor network. Proposed algorithm provides priority both on data and location.
