Comparative analysis of carrier sense multiple access and carrier sense multiple access with shortest first

Abstract

Wireless sensor network consists of thousand of tiny sensor node. Node near base station has heavy load due to load from several surrounding sensor node. Hence, Node near base station use CSMA to forward data to base station. CSMA/SF is addition of priority to CSMA. This Paper compare CSMA and CSMA/SF for reducing energy consumption of sensor node to ameliorate lifetime of wireless sensor network using Network Simulator 3. It also comprises theoretical analysis to prove energy consumption reduction in carrier sense.
