Abstract

MAC protocols have direct control over radio which is the most energy consuming part of a wireless sensor node. TDMA based WSN MAC protocols are more energy-efficient than contention based counterparts. However, classical TDMA based protocols are not appropriate for event driven WSN applications. There are some MAC protocols assigning time slots to only source nodes. Our proposed protocol assigns a time slot to one of the source nodes with same data. As a result it reduces data redundancy achieving energy savings. The analytical expressions are given for the proposed MAC and its performance is compared to the conventional E-TDMA protocol.
