Problem statement:The main idea is to design an energy efficient algorithm for reducing the amount of overhearing based on RSS value in a Mobile Ad-hoc Network (MANET). Approach: A cross layer framework is designed by combining the physical, MAC and network layer. RSS value is taken from the physical layer and it is used for finding the Mobility Parameter (MP). MP value determines the level of overhearing and rebroadcast probability. The energy conservation is achieved by integrating the 802.11 PSM with DSR. In 802.11 PSM, all the nodes are in low power sleep state, but the disadvantage here is unconditional overhearing. So, a conditional overhearing mechanism is proposed based on mobility parameter to reduce the energy consumption. This mechanism reduces energy consumption but at the same time, the node mobility results in more stale routes in route cache of DSR over a period of time. This occurs due to the lack of route cache updation. In the proposed design, RSS value determines whether to select the link or not prior to the route discovery process. Results: Simulation results are compared for Packet Delivery Ratio (PDR) and energy consumption. MP based conditional overhearing shows a 3.2% PDR improvement. It achieves a 20% power saving, if the pause time crosses 300 sec. For the packet injection rate of 2 packets/sec, under no mobility condition, it utilizes 50 joules lesser energy consumption compared to Random Cast. Conclusion: The NS-2 simulation results reveal that the proposed work is energy efficient by reducing the amount of overhearing and also it eliminates the stale routes compared to the classical methods.

Problem statement:This article proposes the selection of best paths in Mobile Ad Hoc Network (MANET) based on multipath routing with fuzzy cost in respect of the Fuzzy Cost Enabled Cluster based Routing (FCECR). Approach: By implementing FCECR, we have made changes to reduce the cost and route discovery overhead for the selection of best path from multipath routing from source to destination node. Results: Results are found in NS2 simulator that cost factorinfluence the network traffic and bandwidth consumption. Besides, it exposes effective changes of network topology. Conclusion/Recommendations: It is shown that the proposed method is used to cluster hierarchal structure management to look for selection of effective path. Future work will be evaluated by implementing the algorithm related to other parallel architectures.
