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: 𝑚,𝑛,𝑘,𝑁_𝑡 and 𝑁_𝑟.

(4) Implement the FEC scheme based on RS coder.

(5) Obtain the value of SNR_TE and 𝑚_max 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 (𝑁_𝑡,𝑁_𝑟) channel.

(10) If timer matures or NACK packet is received

     go to Step (1).

(11) end if
