Wake up after transmissions and reduced channel contention to alleviate the hidden terminal problem in preamble sampling WSNs
The hidden terminal problem is a well-known problem in wireless networks that degrades the network performance due to collisions between nodes unable to sense each other. Preamble sampling WSNs are more sensitive to that problem than wireless local area networks due to the high vulnerability time caused by the long preamble transmission. This is specially important when the traffic load is high...
متن کاملFrame Preamble MAC for MultihopWireless Sensor Networks: Design and Implementation?
MAC protocols based on preamble sampling techniques offer significant energy savings for low datarate multihop wireless sensor networks by efficiently reducing idle listening in lightly loaded networks. However, without any particular optimization, preamble sampling protocols still consume large amounts of energy due to the overhead induced by the long preamble transmitted prior data frames. To...
متن کاملA Preamble Pattern Identification based Synchronization System for UWB-based Wireless Networks
In this paper, we address a preamble pattern identification based synchronization system for UWB-based distributed wireless networks. A correlation based preamble pattern identification method is introduced. A network domain division and nodes tree setting approach according to the principle of Voronoi diagram is proposed and discussed. Therefore, synchronization concluding not only synchroniza...
متن کاملAn Analytical Study of Variable Preamble Length-Based Broadcasting Scheme for WSNs
In this paper, we present a detailed analytical study of previously proposed variable preamble length-based broadcasting scheme for wireless sensor networks (WSNs). Analytical results show that in dense wireless sensor networks, broadcasting a packet with a small size preamble can significantly improve the energy conservation on already limited battery powered sensor nodes. For fairer compariso...
متن کاملA Preamble-Based Broadcasting Technique for Wireless Ad Hoc Sensor Networks
Broadcasting is a fundamental operation in any wireless networks, more so in wireless ad hoc sensor networks, where each sensor node has limited transmission range and battery power. Although broad-casting in wireless ad hoc sensor networks has many advantages but it can cause serious problems like—broadcast storm, which could cause a lot of contention, redundant, retransmission, collision and ...
