Abstract: Advancements in wireless sensor network technology (WSN) have lead researchers to work on wide variety of distributed sensing applications. They have better potential to work without human attention after deployment in large physical environments. Out of all large physical environments that sensing is dealt with, Critical infrastructure monitoring (CIM) emerges as a prominent application. The Major requirements of CIM are reliable data transfer and long deployment life time. These networks are also expected to operate in extremely low-cost communication environment. In this paper we propose a DCF integrated MAC (Medium access control) protocol to cater CIM with better throughput. We have used an infrastructure based wireless sensor network in association with back off algorithm. The simulation shows that DCF integrated channel access method would offer better throughput for CIM which happens to be one of the major requirement.
