アブストラクト
  We study about 2-gateway tandem multi-hop wireless networks with lossy unreliable wireless links. Due to the nature of wireless radio communications, interference can make conflict and result in collapse of messages. In response to this problem, scheduling in message transmission and retransmission (for lost messages) is required. We model a static global assignment of time slots for message transmission on each link and a static message selection on each assigned link for proactive redundant transmission in general and in a simplified way. To find a good message scheduling of this static time slot assignment, we apply mathematical optimization problem. We formulate a static assignment on the number of time-slots assigned to a message on a link. By using Lagrange method, we find ’relaxed’ optimal solution. Afterwards, we check integer solution that maximizes success delivery probability. We conclude that our proposed method performs an optimal solution. However, the dynamic node-local message selection should be adopted for global time slot assignment towards entire message scheduling system.
