Optimized power management for multi hop mobile adhoc networks

MANETs are the networks in which each node communicates with the help of an instant infrastructure in the network. Hence these networks have great dependence on its battery power. The battery power has greater influence on the overall life time of the network. In the network, to demote the power various power saving techniques are used. One such method is the power management techniques in which the nodes are made to sleep and wake up in regular intervals. The repeated pattern is scheduled to manage the power efficiently. In the proposed methodology, Optimized Hyper Quorum Systems (OHQS), the structure of beacon period is changed to demote the power used by each node in the network. Further OHQS is enhanced to make the new beacon structure work effectively. This makes the nodes with different Repetition Pattern Interval (RPI) communicate effectively with increasing throughput. Also better trade off is made between the latency and the power used in the network. Thus the proposed algorithm gives the nodes a greater probability to discover any other nodes, which makes the communication effective. The simulation results show better energy saving, throughput, Packet Delivery Ratio (PDR).
