I need to develop WSNs that contains some selfish nodes. All sensor nodes in the network should be fully functional. It means that these sensor nodes have the ability to sense and send their information to the base station by their neighbor nodes via multihop routes and as well as forward their neighbor information. All nodes should maintain the routing table about their neighbors. This wsns then show that if the selfish nodes inside will drop the packets for other nodes. According to this situation the data should be included in some file to show that it affects the functioning of the WSNs.
