Enhancing Cellular Coverage Quality by Virtual Access Point and Wireless Power Transfer

Algorithm 1

VAP election.

Run at the macro base station

Input:

Output:

  Determine the number of virtual access points (e.g., 6)

  Set their reference coordinates (e.g., the positions of dotted triangle shown in Figure 1)

  For each reference coordinate point (e.g.,) do

   Broadcast a request packet at its maximum transmission power

   Set and as 0 and a very large value respectively

   Set the timer as

   while the timer does not expire do

    If receive a responding packet from node   then

      If    then   and   End if

    End if

   End while

   Add to

   Send a confirmation package to node

  End for

Run at any node

Input: null

Output: null

  If receive a requesting packet with a reference point (e.g.,) then

     If   and   then

    Send a response packet to MBS

     End if

  End if

  If receive a confirmation with a reference point (e.g.,) then

     Mark itself as the virtual access point with respect to the reference coordinate point

  End if
