TAS-MAC: A Traffic-Adaptive Synchronous MAC Protocol for Wireless Sensor Networks
Chin-Jung Liu, Pei Huang, Li Xiao
Article No.: 1
Duty cycling improves energy efficiency but limits throughput and introduces significant end-to-end delay in wireless sensor networks. In this article, we present a traffic-adaptive synchronous MAC protocol (TAS-MAC), which is a high-throughput,...
Optimizing the Lifetime of Sensor Networks with Uncontrollable Mobile Sinks and QoS Constraints
Francesco Restuccia, Sajal K. Das
Article No.: 2
In past literature, it has been demonstrated that the use of mobile sinks (MSs) increases dramatically the lifetime of wireless sensor networks (WSNs). In applications where the MSs are humans, animals, or transportation systems, the mobility of...
This article demonstrates how to use multiple channels to improve communication performance in Wireless Sensor Networks (WSNs). We first investigate multichannel realities in WSNs through intensive empirical experiments with Micaz motes. Our study...
Near-Optimal Deterministic Steiner Tree Maintenance in Sensor Networks
Gokarna Sharma, Costas Busch
Article No.: 4
We consider the group-communication maintenance problem between a set of k mobile agents that are tracked by a static sensor network. We develop a scalable deterministic distributed algorithm for maintaining a Steiner tree of the agents so...
Decentralized Network-Level Synchronization in Mobile Ad Hoc Networks
Spyros Voulgaris, Matthew Dobson, Maarten Van Steen
Article No.: 5
Energy is the scarcest resource in ad hoc wireless networks, particularly in wireless sensor networks requiring a long lifetime. Intermittently switching the radio on and off is widely adopted as the most effective way to keep energy consumption...
ATPC: Adaptive Transmission Power Control for Wireless Sensor Networks
Shan Lin, Fei Miao, Jingbin Zhang, Gang Zhou, Lin Gu, Tian He, John A. Stankovic, Sang Son, George J. Pappas
Article No.: 6
Extensive empirical studies presented in this article confirm that the quality of radio communication between low-power sensor devices varies significantly with time and environment. This phenomenon indicates that the previous topology control...
Monitoring Bats in the Wild: On Using Erasure Codes for Energy-Efficient Wireless Sensor Networks
Falko Dressler, Margit Mutschlechner, Bijun Li, Rüdiger Kapitza, Simon Ripperger, Christopher Eibel, Benedict Herzog, Timo Hönig, Wolfgang Schröder-Preikschat
Article No.: 7
We explore the advantages of using Erasure Codes (ECs) in a very challenging sensor networking scenario, namely, monitoring and tracking bats in the wild. The mobile bat nodes collect contact information that needs to be transmitted to stationary...
