摘要：Wireless sensor networks face a challenge while transmitting datawhich is under jamming. Jammer interferes with the physicaltransmission and affects the traffc in the network. Jammingmay occur due to various causes like sending multiple packetsthrough single path or sending multiple packets through multiplepaths. It may occur even when continuous noise is generated withsuffcient power near the transmitting or receiving nodes. Jammercauses this noise which may also lead to path loss. There are manymechanisms and techniques to overcome this problem. Varioussource routing protocols like Dynamic Source Routing, AODV areused to route the packets to the path where jamming does not occur.One of the main problems in jamming is Centralized Optimizationproblem which is solved by using distributed algorithm. Anotherimportant technique which is used to solve flow optimizationproblem is portfolio selection theory which fnds the less riskypaths so that the packets can be directed towards it. In this paper,we use a protocol to prevent jamming. Our proposed mechanismis Geographical Routing Protocol and queuing manager algorithmwhich sets priority to the packets that sends it across the nodes.
