PPR: Partial Packet Recovery for Wireless NetworksKyle Jamieson and Hari BalakrishnanMIT Computer Science and Artificial Intelligence Lab{jamieson, hari}@csail.mit.edu AbstractBit errors occur over wireless channels when the signal isn’t strong enough toovercome the effects of interference and noise. Current wireless protocols may useforward error correction (FEC) to correct for some (small) number of bit errors,but generally retransmit the whole packet if the FEC is insufficie ...دانلود مقاله Comparing ARQ and HARQ Protocols for WSN and MIMO SYSTEMS
Comparing ARQ and HARQ Protocols for WSN and MIMO SYSTEMS Student:Praveen Francis RegoMatriculation Number: 30104837Supervisor:Marc Selig September, 2011 AbstractA major concern in data communications is the effective and efficient control of transmission errors caused by channel noise so that error-free data can be delivered to the user. In view of this concern, to achieve error-free data, various Data Link Layer error-control schemes were proposed. Automatic-repeat-request (ARQ) schemes and Hy ...دانلود مقاله OPERA: An Optimal Progressive Error Recovery Algorithm for Wireless Sensor Networks

J Inf Process Syst, Vol.8, No.4, December 2012 R.Sumathi* and M.G.Srinivas** Abstract—With the increasing demand for real time applications in the Wireless SenorNetwork (WSN), real time critical events anticipate an efficient quality-of-service (QoS)based routing for data delivery from the network infrastructure. Designing such QoSbased routing protocol to meet the reliability and delay guarantee of critical events whilepreserving the energy efficiency is a challenging task.
