The detailed description of simulation setup is referred to Sect. Therefore we formulate a longest path problem as follows. Mak, T., Cheung, P.Y., Luk, W., Lam, K.P. Dynamic programming (DP) is a general algorithm design technique for solving problems with overlapping sub-problems. We define a longest path problem to optimize the router lifetime by routing packets along the path with maximum lifetime budgets. We conduct a case study to show the distribution of routers reliability under two different routing algorithms, XY and Oddeven.

So, if we duplicate the devices at each stage then the reliability of the system can be increased. Before we study how … The key idea is to save answers of overlapping smaller sub-problems to avoid recomputation. Extrinsic failures are caused by manufacturing defects and occur with a decreasing rate over time. The problem is solved by dynamic programming approach with linear time complexity. If r1 = 0.99 and n = 10 that n devices are set in a series, 1 <= i <= 10, then reliability of the whole system πri can be given as: Πri = 0.904.
