ABSTRACT Wireless sensor networks have been widely used in many important fields. Medium Access Control (MAC) protocols have a significant effect on the function and performance of sensor networks. At present, most MAC protocols use the same transmission power when sensor nodes send packets. However, the deployment of the sensor nodes is asymmetrical in wireless sensor networks, which will bring more energy consumption and unnecessary collisions. By jointing the MAC layer and physical layer of the senor nodes, and based on Sensor MAC (SMAC) [1] protocol, we propose a transmission power control MAC protocol in wireless sensor networks (transmission Power control in SMAC, PSMAQ. The simulation results show that, compared with the SMAC protocol, our protocol has improved a lot in the delay of packets, reception rate, energy consumption and throughput of the networks.

    ABSTRACT: Wireless sensor networks (WSN) have been widely used in many important areas. Medium access control (MAC) protocols have a significant influence on the function and performance of WSN. In existing protocols such as sensor MAC (SMAC), the sensor nodes reduce energy consumption by introducing an active/sleep duty cycle, which always leads to more control packets. These control packets waste a lot of energy. Other contention-based MAC protocols either cannot solve the idle listening or fail to consider the complexity of the protocol. Based on SMAC, we propose a novel contention-based MAC protocol, which decreases the control packets by modifying the control packets message and canceling time synchronization. The simulation result indicates that the performance of our protocol is much better than that of SMAC protocol in energy consumption.

    ABSTRACT: In this paper, we propose an asynchronous MAC protocol to maximize energy efficiency for a wireless sensor network in multi channel environments. Our proposed SPMC- MAC (Slim Preamble Multi-Channel Media Access Control) adopts the preamble sliming mechanism proposed in (6) that takes advantage of the knowledge about the wakeup time of the receiver node. The preamble contains the receiver's ID and a randomly selected channel ID for data communication, and it is transmitted over a dedicated common channel. To handle traffic load variations in time and location, a sender in SPMC-MAC communicates over a randomly selected channel for load distribution and uses an adaptive power control according to the node density. The power control has the benefit of keeping an appropriate number of nodes with the communication range, resulting in reduced collision and interference. Against X-MAC that uses divided short preambles, SPMC-MAC is able to minimize energy consumption much more at the sender side. Through simulations, we compare our SPMC- MAC and X-MAC extensively in terms of energy consumption and throughput. SPMC-MAC achieves much reduction in energy consumption and increases in throughput compared with X-MAC owing to the use of multi channels and power control.

    ABSTRACT: Wireless sensor networks have been widely used in many important areas. Medium access control (MAC) protocols take charge of the distribution and administration of sensor network's wireless channel, and have a significant influence on the function and performance of sensor networks. Most traditional MAC protocols do not consider traffic loads directly, but the amount of traffic affects the efficiency of channel assignment and energy utilization. This paper summarizes existing wireless sensor network MAC protocols, and proposes a novel traffic queue-aware sensor MAC protocol (QSMAC) which is based on sensor MAC (SMAC) protocol and can predict the amount of data traffic in network with the average increase rate of data packets in a node's buffer queue. The simulation indicates that the performance of our protocol is much better than that of SMAC protocol in data packet's delay, the consumption of energy, the reception ratio of data packets and the throughput of the network.
