  1. Energy Efficiency and Routing in WSNs Source Source Sink Sink Multiple rate applications: A scenario

  2. 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.
