Power Saving MAC Protocols for WSNs and Optimization of S-MAC Protocol
Low power MAC protocols have received a lot of consideration in the last few years because of their influence on the lifetime of wireless sensor networks. Since, sensors typically operate on batteries, replacement of which is often difficult. A lot of work has been done to minimize the energy expenditure and prolong the sensor lifetime through energy efficient desi...
متن کاملA Power Saving MAC Protocol for Wireless Networks
This paper presents a protocol which improves on the power saving mechanism in the IEEE 802.11 Distributed Coordination Function (DCF). In the power saving mechanism (PSM) for DCF, all nodes are synchronized by beacons. In each beacon interval, there is a fixed time interval called the ATIM window where every node has to be awake. During the ATIM window, a source node informs a destination node...
متن کاملModeling and Performance Evaluation of Energy Consumption in S-MAC Protocol Using Generalized Stochastic Petri Nets
One of the features of wireless sensor networks is that the nodes in this network have limited power sources. Therefore, assessment of energy consumption in these networks is very important. What has been common practice has been the use of traditional simulators to evaluate the energy consumption of the nodes in these networks. Simulators often have problems such as fluctuating output values i...
متن کاملTSTP MAC: a Cross-Layer, Geographic, Receiver-Based MAC Protocol for WSNs
In Wireless Sensor Networks (WSNs), energy saving is a big concern. Radio transceivers are a major source of energy consumption and it is generally desirable to turn them on for just a fraction of the time, but this brings a trade-off between energy saving and latency and/or node availability. TSTP MAC is a cross-layer Medium Access Control protocol which is part of TSTP – an application-orient...
متن کاملComparing Energy-Saving MAC Protocols for Wireless Sensor Networks
Applications for wireless sensor networks have notably different characteristics and requirements from standard WLAN applications. Low energy consumption is the most important consideration. The low message rate that is typical for sensor network applications and the relaxed latency requirements allow for significant reductions in energy consumption of the radio. In this article we study the en...
