Revisiting Clustering Based Efficient Broadcast for Wireless Multihop Networks with Memory Limited Nodes [chapter]

Rafael Funke, Hannes Frey
2010 Lecture Notes in Computer Science  
The easiest way to broadcast a message in a wireless multihop network is to let each network node retransmit the broadcast message once it has received it.  ...  Solutions described so far either guarantee that all nodes in the network are reached but suffer from nodes with strict memory limitations, or can be applied on nodes with memory limitations but sacrifice  ...  An interesting question arises on how much memory is typically required in common wireless network scenarios to perform standard clustering based on the knowledge of neighbor nodes.  ...

Reprogramming wireless sensor networks: challenges and approaches

Qiang Wang, Yaoyao Zhu, Liang Cheng
2006 IEEE Network  
Due to capacity constraints of sensor nodes, a monolithic program with too many functions cannot be fitted into the memory.  ...  Abstract Wireless sensor networks need an efficient and reliable reprogramming service to facilitate management and maintenance tasks.  ...  Characteristics of Wireless Sensor Networks Unlike reprogramming on other platforms (e.g., PCs), a reprogramming service for WSNs must run on sensor nodes with very limited resources.  ...

Real-time communication and coordination in embedded sensor networks

J.A. Stankovic, T.F. Abdelzaher, Chengyang Lu, Lui Sha, J.C. Hou
2003 Proceedings of the IEEE  
Sensor networks can be considered distributed computing platforms with many severe constraints, including limited CPU speed, memory size, power, and bandwidth.  ...  Individual nodes in sensor networks are typically unreliable and the network topology dynamically changes, possibly frequently.  ...  Existing MAC protocols for multihop wireless networks can be classified into four categories: 1) scheduling based; 2) collision free; 3) contention based; and 4) hybrid schemes.  ...

Data Pouring and Buffering on the Road: A New Data Dissemination Paradigm for Vehicular Ad Hoc Networks

Jing Zhao, Yang Zhang, Guohong Cao
2007 IEEE Transactions on Vehicular Technology  
In DP, data are periodically broadcast to vehicles on the road. In DP with intersection buffering (DP-IB), data poured from the source are buffered and rebroadcast at the intersections.  ...  To support VANET-based applications, it is important to disseminate data from an information source (data center) to many vehicles on the road.  ...  As a result, many well-studied structures for efficient data dissemination, such as trees, clustering, and grids, are extremely hard to set up and maintain.  ...
