International Journal of Signal Processing Systems Vol. 3, No. 1, June 2015 R. C. Choukimath and V. V. Ayyannavar Abstract—Message authentication is one of the most effective ways to thwart unauthorized and corrupted messages from being forwarded in wireless sensor networks (WSNs). For this reason, many message authentication schemes have been developed, based on either symmetric-key cryptos ...

Liankuan Zhanga, Deqin Xiaob, Procedia Engineering 29 (2012) 1492 – 1500 Available online at www.sciencedirect.com  SciVerse ScienceDirect AbstractAs Bit errors fluctuate wildly in different environments and they fluctuate steadily for a givenpair of sensor nodes, we propose an error-aware routing protocol (EARP). Compared to otherestimators, bit errors can directly reflect the wireless ...

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, variou ...

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 ...
