Reliable Routing Design in Predictable Wireless Networks with Unreliable Links

In this paper, the reliable routing design problem is investigated in predictable wireless networks over unreliable links. The predictable wireless networks are described as a sequence of static graphs, and then modeled as a space-time graph. The reliable routing design problem on the space-time graph is defined as a bi-objective optimization problem. The aim of the new routing design problem is to find a routing path with the maximum routing reliability and the minimum routing cost. Next, a hierarchical shortest routing algorithm is proposed to find the feasible routing path. Simulation results validate the effectiveness of the proposed routing algorithm.
