Neighbor Detection Power Control (NDPC) MAC protocol in mobile ad hoc networks

Abstract

Media access control (MAC) protocol design is a challenging problem in wireless ad hoc networks. Network resource management like battery life and bandwidth are two design factors in these networks. Some power control MAC protocols try to increase throughput or decrease energy consumption or both of them. We propose a power control scheme based on number of neighbor in mobile ad hoc network and consider both physical and connectivity design issues. There is a trade off between physical and network connectivity when transmission power is selected. With knowledge of local information on network, we can influence global network statistics. If the number of one-hop neighbors increase, then the transmission power will decrease, and vice versa. Simulation results show better performance of our protocol in energy consumption and throughput in various scenarios and mobility models.
