Abstract

Ad hoc networks have recently been used as a communications medium on tasks that require high levels of communication and coordination. We study the problem of determining an optimal route for a group of wireless units, such that the total connection time among nodes in the resulting mobile ad hoc network is maximized, subject to a limit on the traveled distance. This problem, called the cooperative communication problem in mobile ad hoc networks (CCPM), is modeled using combinatorial optimization and mathematical programming techniques. Applications occur on the coordination of rescue groups, geographical exploration and recognition, unmanned air vehicles (UAVs), and mission coordination. The problem is shown to be NP-hard, and a dynamic programming algorithm is proposed for the problem. Mathematical programming models are presented and computational experiments performed.
