摘要：Wireless sensor networks face a challenge while transmitting data which is under jamming. Jammer interferes with the physical transmission and affects the traffic in the network. Jamming may occur due to various causes like sending multiple packets through single path or sending multiple packets through multiple paths. It may occur even when continuous noise is generated with sufficient power near the transmitting or receiving nodes. Jammer causes this noise which may also lead to path loss. There are many mechanisms and techniques to overcome this problem. Various source routing protocols like Dynamic Source Routing, AODV are used to route the packets to the path where jamming does not occur. One of the main problems in jamming is Centralized Optimization problem which is solved by using distributed algorithm. Another important technique which is used to solve flow optimization problem is portfolio selection theory which finds the less risky paths so that the packets can be directed towards it. In this paper, we use a protocol to prevent jamming. Our proposed mechanism is Geographical Routing Protocol and queuing manager algorithm which sets priority to the packets that sends it across the nodes.
