Abstract: Power control is one of the essential technical of energy aware Mobile Ad-hoc Networks (MANETs) and has gained much attention. Power control can reduce energy consumption but it also brings more collisions and frequent changes of network topology. In this project, we propose a comprehensive solution for power control in Mobile Ad-hoc Networks. Our solution emphasizes the combination on both power control and multi-channel and combination on the MAC layer and network layer. Our solution is characterized by the following features: it uses independent channels to transfer data packets to reduce collisions in data transmission, it uses maximum power level to transfer control packets and proper power to transfer data packets, as a result energy consumption is reduced, network connectivity is guaranteed and frequent change of network topology is eliminated at the same time, this idea inspired from POWMAC and PCDC protocols. It employs POWMAC protocol which is intended to allow for multiple transmissions to take place within the same neighborhood that leads to an increase in network throughput and possibly a reduction in the overall energy consumption. This protocol provides proper solution to the hidden and exposed terminal problem in wireless ad hoc network and improves the network performance. The performance of MC-POWMAC protocol is tested. Experiments show that MC-POWMAC protocol is suitable to solve the problem of hidden and exposed terminal in multi-hop wireless networks and can control the power more effectively to reduce the energy consumption of network nodes for prolonging the life of the entire network. Simulation results emphasize that the performance of MC-POWMAC is better than that of POWMAC and 802.11 where we increased the throughput from 50% in POWMAC to 74% in our suggested protocol.
