WCP and WCPCap: Congestion Control for Multi-hop Wireless Mesh Networks
WCP and WCPCap are congestion control schemes for multi-hop wireless networks with any-to-any traffic pattern. WCP is a rate-based, end-to-end distributed congestion control scheme that shares congestion status and average RTTs of flows in a neighborhood to achieve fairness through correct congestion signaling and rate clocking of all the flows in the network. In contrast, WCPCap is an explicit rate feedback scheme that estimates spare capacity in a neighborhood and apportions it fairly among flows traversing the neighborhood. WCP and WCPCap has been implemented in Qualnet while WCP has also been implemented for Linux using Click Modular Router.

IFRC: Interference-Aware Fair Rate Control
IFRC is a distributed congestion control scheme for wireless sensor networks. For a wireless network consisting of N nodes sending data to a single base station (many-to-one traffic pattern) over multiple hops, IFRC provides fair and efficient rate to all the flows in the network. IFRC has been implemented on Tmote Sky, a wireless sensor networks platform.

Wisden: Wireless Sensor Network for Structural Health Monitoring
Wisden is a wireless sensor network based data acquisition system for structural health monitoring. Consisting of reliable data delivery, data synchronization and data compression schemes it provides support for data acquisition of vibration data up to 200Hz along 3-axes. Wisden had been deployed on a real building (which was shaken using hydraulic shakers) and a seismic test structure.
Experience gained from Wisden has resulted in Tenet, a new architecture for sensor networks. Wisden had now been developed as an application on Tenet architecture.
