Energy-Efficient Adaptive Geosource Multicast Routing for Wireless Sensor Networks

Algorithm 4

Path serializing for unicast.

Input: node

Output: a branch or a destination node

 (1) if  IsBranch(node) then

 (2)  return node

 (3) end if

 (4) // a leaf node

 (5) if  node→left == Null then

 (6)  return node

 (7) end if

 (8) PathSerializingForUnicast(node→left)
