Journal ArticleDOI
TL;DR: It is concluded that the APTEEN protocol is the most suitable routing strategy to precision farming and its network lifetime can reach 6.5 month which is a period more than the maximum value of the potato crop lifetime that estimated to be 120 day, but it is greater than the yearly cultivation period of potato in Egypt which reaches 6 month.
