Energy-Aware TDMA-Based MAC for Sensor Networks

Abstract: Networking unattended sensors is expected to have a significant impact on the efficiency of many military and civil applications. Sensors in such systems are typically disposable and expected to last until their energy drains. Therefore, energy is a very scarce resource for such sensor systems and has to be managed wisely in order to extend the life of the sensors for the duration of a particular mission. In this paper, we present a novel approach for energyaware management of sensor networks that maximizes th… Show more

“…In contrast to CSMA, scheduled-based TDMA (timedivision multiple access) [17][18][19][20][21] techniques offer an inherent collision-free scheme. The first advantage of TDMA is that interference between adjacent wireless links is guaranteed to be avoided.…”

“…TDMA protocols can be classified as randomized (e.g., [9][10][11]) and and deterministic protocols (e.g, [6,12]). In [9], whenever a collision occurs during startup (synchronization phase), exponential backoff is used for determining the time to transmit next.…”

“…The complexity of this algorithm is where is the diameter of the network, and deterministic startup algorithm is used to assign time slots to different sensors. In [12], Arisha et al propose a clustering scheme to allot time slots to different sensors. Each cluster has a gateway node.…”

“…Missionoriented organization of the sensor network enables the appropriate selection of only a subset of the sensors to be turned on and thus avoids wasting the energy of sensors that do not have to be involved [6]. In addition, energy-aware routing of communication traffic and medium access arbitration among sensors extend the network lifetime [7].…”
