PSO and OLSR Based Protocol for Cognitive Radio Sensor Network
R G Gangambika, Badarla Sri Pavan · 2017
The wireless sensor network (WSN) operates in the public unlicensed spectrum band, which has become increasingly crowd because of the emergence of the vast wireless communication technologies. To solve such problems in WSN the cognitive radio sensor networks (CRSN) have been proposed. The CR enables the opportunistic access to unused licensed bands; here the CR allows secondary users to access the free portion of the licensed spectrum. C0gnitive wirelesssensor networks, co-existing with the wirelesssensor networks are also dependent on the fixed energy resources. Here in this paper main goal is to develop the energy efficient protocol for the CRSN which should increase the network lifetime. Hence we are using PSO and OLSR protocol in the proposed system.
