Energy-Aware Adaptive Cooperative FEC Protocol in MIMO Channel for Wireless Sensor Networks
Algorithm 1
Algorithm of ACFEC at sender node.
Input: Parameters of ACFEC scheme | Output: Data packets | (1) Carry out the combination scheme of RS coder and MIMO channel. | (2) Appoint the guarantee priority of reliability. | (3) Initialize the network parameters: and . | (4) Implement the FEC scheme based on RS coder. | (5) Obtain the value of SNRTE and based on the QoS analytical model. | (6) If channel state information is known | (7) Implement the relay selection mechanism. | (8) end if | (9) Encapsulate data packets by means of MIMO () channel. | (10) If timer matures or NACK packet is received | go to Step (1). | (11) end if |
