Large Sensor Networks | http://ns2code.com/
Wireless sensor networks (WSNs) are typically constituted by a large number of connected sensors (nodes), generally distributed at random on a given surface area.
Reason to introduce large sensor networks:
• Full network connectivity
• High coverage of the sensing area
• Reduced power consumption
• Capacity
• Clocks
• Function computation
Concepts present in large sensor networks:
• To maintaining sensing coverage and connectivity in WSN
• for density control in large scale sensor networks
• self-organization of the swarm into large-scale structures that reflect the structure of the street network
• analyze algorithms for clock synchronization
• to reliably compute a composite function of sensor measurements
• energy efficiency
• computation and memory
• analyze potentially frequent node failures
• minimum number of nodes required to achieve full network connectivity
• How to further diminish network energy consumption by switching off some of the active nodes at random etc.
