چکیده

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.

Exploiting spatial correlation at the link layer for event-driven sensor networks

Wireless sensor networks (WSNs) can generally be classified into two categories: timedriven and event-driven. In an event-driven WSN, sensors report their readings only when they detect events. In such behavior, sensors in the event area may suffer from higher contention. In this paper, we solve this problem by jointly considering two subissues. One is exploiting the spatial correlation of data...

An Adaptive MAC Protocol for Efficient Group Communications in Sensor Networks

This paper proposes a novel adaptive energy efficient MAC protocol for wireless sensor networks, referred to as TDMA-WA. The proposed protocol is contention free and is based on the well known timedivision multiple access (TDMA) principle. However, the frame length is variable corresponding to the degree of 2hop neighborhood for each node. This allows the frame length to adapt to the varying de...

Location Based Zonal QoS Routing Protocol in Mobile Ad Hoc Networks

In M2M communication, there is critical requirement of robust MAC protocol to enable multiple M2M devices to access the channel. For this purpose, a frame based hybrid MAC protocol consisting of CSMA-based contention period and TDMA based transmission period is presented in the literature. During contention period, the devices compete for the channel access and those devices which win a slot in...

TDMA Protocols with Reduced Frame for Wireless Sensor Networks

TDMA-based MAC protocols, in its traditional form, suffer from low channel utilization and high message delay because of a long frame length needed to provide collision-free transmissions. In this paper, we introduce a class of TDMA-based protocols, called reducedframe TDMA, which allow conflicting slot assignments, but provide every TDMA slot with a short time period dedicated for CSMA-based c...
