A Blockchain-Based Contractual Routing Protocol for the Internet of Things Using Smart Contracts

Algorithm 1

Route Request function.

1:  function ROUTE REQUEST(DESTINATION, RRB, RRE, BLACKLIST, PARENTADDRESS(OPTIONAL), HOP(OPTIONAL) )

2:   Transfer tokens from the function caller to the block producer.

3:   Transfer tokens from the function caller to the current contract address

4:   Set to

5:   Set to

6:   if this is an original smart contract then

7:    Set to

8:   end if

9:   if this is an intermediary smart contract then

10:   Set to Hop

11:   Set to ParentAddress

12:  end if

13:  Set to

14: end function
