Abstract Abstract. In the area of wireless sensor networks, achieving minimum energy consumption is a very important research issue. A number of energy efficient protocols have been proposed, mostly based on a layered design approach, which means that they are focused on designing optimal strategies for “single ” layer only. In this paper, we take an alternative approach i.e., a cross-layer design, and present a new MAC protocol named MAC-CROSS. In this new approach, the interactions between MAC and Routing layers are fully exploited to achieve energy efficiency for wireless sensor networks. More precisely, in the proposed MAC-CROSS algorithm, routing information at the network layer is utilized for the MAC layer such that it can maximize a sleep duration of each node. Through implementation on a Mica Mote platform and simulation study using the NS-2, we evaluate a performance of the presented MAC-CROSS and prove its substantial performance gains.
Energy Efficient Protocols For Active Rfid
Apr 19, 2017 - Wireless Passive Sensor Networks (WPSNs) and MAC protocols are. MAC protocols for WPSNs only need to consider saving energy. As MAC layer regulates the activities of the radio layer, which consumes the most energy, then we can deduce that the MAC protocol can avoid energy wastage, hence reach the goal of energy efficiency. Adaptability: In most applications of WSNs, traffic density varies significantly over time and from part of the network to another [ 9, 10 ].
