Power Saving Mechanism for Ad-Hoc Network using 3G Fast Dormancy Technology

摘要

The 3G devices known for higher energy consumption. The energy demand can be minimized by avoiding unnecessary listening between the nodes using fast dormancy. The fast dormancy mechanism has been implemented in ad-hoc network. Thus the channel access done by introducing Ad-hoc Traffic Indication Window(ATIM) in ad-hoc network. The ATIM window size is defined in an optimal way. According to the ATIM window behavior the node may enter into awake / sleep state. Making the node in sleep state avoid the nodes overhearing in the network traffic as a result node failure will be avoided and network topology may maintain. The stimulation has been done with 100 nodes based on nodes throughput, energy and delay. The result shows long lived nodes in the network. Thus, the network structure has been maintained by saving nodes energy by implementing fast dormancy. The fast dormancy release the ad-hoc network channel when they no longer needed. The 90 % of nodes alive active to maintain network topology.
