Abstract:
Several studies predict the use of wireless ad hoc networks in support of critical missions like search and rescue and prevention of natural disasters. In order to improve network connectivity, Cooperative Communication (CC) has been explored as an alternative to connect isolated network components in wireless ad hoc settings. However, existing cooperative communication solutions rely on global topological information which may not be feasible in more realistic scenarios. This paper presents a self-organized and distributed solution to improve network connectivity by exploring the availability of cooperative communication links. Simulation results show that the proposed scheme has a low computation cost and provides a link recovery rate comparable to those obtained by centralized solutions.
