Collaborative Wakeup in Clustered Ad Hoc Networks

Shan-Hung Wu, Chung-Min Chen, Ming-Syan Chen
2011 IEEE Journal on Selected Areas in Communications  
The ACQ system guarantees the neighbor discovery between each member node and the clusterhead in a cluster, and between clusterheads in the network.  ...  We show that by taxing slightly more energy consumption on the clusterhead, the average energy consumption of stations in a cluster can reduce substantially than can be achieved by traditional QPS protocols  ...  In QPS protocols, each station performs neighbor maintenance by remembering the awake/sleep schedules of nearby nodes 2 .  ...

Collaborative Algorithms for Communication in Wireless Sensor Networks [chapter]

Tim Nieberg, Stefan Dulman, Paul Havinga, Lodewijk van Hoesel, Jian Wu
2003 Ambient Intelligence: Impact on Embedded Sytem Design  
Scheduling of operations, e.g. for the MAC protocol, is naturally supported by a clustered structure of the network.  ...  These systems are quite different from those of current computer systems, and will have to be based on radically new architectures and use novel protocols.  ...  A node that cannot communicate directly with a clusterhead of another cluster, but can do so with a node that is member of a different cluster, is referred to as a distributed gateway.  ...

Power-aware broadcasting and activity scheduling in ad hoc wireless networks using connected dominating sets

Jie Wu, Bing Wu, Ivan Stojmenovic
2003 Wireless Communications and Mobile Computing  
In this paper, we propose to apply the notion of power-aware connected dominating set to broadcasting and activity scheduling.  ...  Activity scheduling deals with the way of rotating the role of each node among a set of given operation modes (e.g. dominating nodes versus dominated nodes).  ...  Section 3 discusses the proposed power-aware broadcasting and activity scheduling. An example is also included to illustrate different activity-scheduling methods.  ...

State of the Art in Quorum-Based Sleep/Wakeup Scheduling MAC Protocols for Ad Hoc and Wireless Sensor Networks

Eman Alzahrani, Fatma Bouabdallah, Hind Almisbahi, Cong Pu
2022 Wireless Communications and Mobile Computing  
This paper presents a detailed overview and classification of several existing quorum-based sleep/wakeup scheduling MAC protocols.  ...  In energy-constrained networks, designing an energy-efficient MAC protocol is crucial since the MAC protocol controls the access of the nodes to the shared wireless medium.  ...  sleep/wakeup scheduling protocols.  ...

Sensors Lifetime Enhancement Techniques in Wireless Sensor Networks - A Survey [article]

Sami Halawani, Abdul Waheed Khan
2010 arXiv   pre-print
In this paper, we discuss different state-of-the-art protocols both in MAC and routing domains that have been proposed for WSNs to achieve the overall goal of prolonging the network lifetime.  ...  We then discuss how schedule-based and contention-based MAC protocols can contribute to achieve optimal utilization of the limited energy resource by avoiding or reducing the chances of collisions and  ...  However since nodes periodically sleep so an interested sending node must know the listening and sleeping schedule of a neighbor with which it wants to communicate.  ...

Unilateral Wakeup for Mobile Ad Hoc Networks with Group Mobility

Shan-Hung Wu, Jang-Ping Sheu, Chung-Ta King
2013 IEEE Transactions on Mobile Computing  
The authors are with the  ...  To address this problem, we propose a new wakeup scheme, named Unilateral-(Uni-) scheme, for MANETs that allows nodes with slower moving speed to sleep more without losing the network connectivity.  ...  This awake/sleep schedule repeats every n beacon intervals and is called the cycle pattern.  ...

Application oriented connected dominating set-based cluster formation in wireless sensor networks

V. S. Anitha, M. P. Sebastian
2010 Journal of the Brazilian Computer Society  
Clustering is a fundamental mechanism used in the design of Wireless Sensor Network (WSN) protocols.  ...  The performance of WSNs can be improved by selecting the most suitable nodes to form a stable backbone structure with guaranteed network coverage.  ...  To improve power efficiency, a clusterhead schedule activities in its cluster so that the nodes can switch to the low-power sleep mode. This scheduling is done in round-robin order.  ...
