Abstract

Security as well as energy consumption is the main components of wireless sensor network. Sensor node has the main functional component present in the WSN. In order to improve the efficiency of energy consumption, enhanced version of (EC-MAC) is proposed. Emergency Code-Medium Access Control (EC-MAC) is responsible for emergency purposes. The proposed MAC protocol is designed using the Carrier Division Multiple Access (CDMA) mechanism. CDMA can be used to enable multiple users to access shared medium without interference. The main resource of EC-MAC protocol is well suited to change the topology in MAC protocol during emergency mode. The MAC behaviour changes during the change in the topology and may inject the data detection. In order to address these issues, Fuzzy-Concealing Sink Hole (F-CSH) may be used to find the location of the main sink using the fake sink holes to anticipate the traducer to turn the network to deplete the node energy and abunding the network with bogus data. RSSI may be used to estimate the distance between the two nodes during the data transmission.
