The Problem, Existing Solutions & their limitations
Temp monitoring: Sampled at the order of one message in several mins.
CTP, MultihopLQI,Dozer, CentRoute etc..
Surveillance systems: Sampled at the order of several messages per second.
Wisden, QCRA, IRFC, RCRT etc..
Compressed accelerometer bulk data, 100k byte in 10 mins. Packet s inter-related. Single packet loss jeopardize the whole bulk .
RBC, KOALA, RMST, FLUSH etc..
• Limitations:– All protocols support uniform data rate.– In presence of multiple rate traffic the protocols use conservative approach for
resource utilization. E.g: Temperature readings and accelerometer data on collected from the same network.
