Abstract:
Wireless Sensor Networks (WSNs) have emerged to meet the multimedia requirements in new emerging applications. So it’s important for WSN to have an adaptive and energy-efficient TDMA-CSMA based MAC protocol which significantly reduces energy consumption of the network. Here, this study proposes an Adaptive MAC protocol with effective TDMA time-slot assignment and CSMA contention window adaptation for WSN. This approach mainly consists of two parts which are TDMA time-slot assignment and CSMA contention window adaptation. Through TDMA time-slot assignment it is possible for the receiver nodes to re-organize the timeslots among the sender nodes according to their accessible traffic load. Through CSMA contention window, the network can reduce the latency occurring between the nodes during the transmission.

Key words:  Carrier Sense Multiple Access (CSMA), latency, MAC protocol, Time Division Multiple Access (TDMA), time-slot assignment, Wireless Sensor Networks (WSNs),
