Coverage extension based on incentive scheduler for mobile relaying nodes in wireless networks

Abstract

In this paper, we propose a new scheduler able to extend the wireless coverage by using an incentive approach for potential mobile relaying nodes. Indeed, the cost of cooperation can be expensive in terms of QoS and energy consumption which do not motivate the nodes to cooperate. Our incentive approach rewards the cooperative nodes. The percentage of cooperation is considered in the QoS management in order to incite the border nodes to cooperate and then to extend the wireless area. Moreover, the monitoring mechanism is proposed to correctly evaluate the cooperation rate of each node. The results show that not only the proposed solution allows the border nodes to cooperate without the negative impact but also enhance the QoS parameters.
