Energy Efficient Reliable Routing Algorithms for Wireless Ad-hoc Network

To address the problem of energy efficient reliable routing in wireless networks in the presence of unreliable communication links or devices or lossy wireless link layers by integrating the power control techniques into the energy efficient routing. This work deals with the problem of energy-efficient reliable wireless communication in the presence of unreliable or loss wireless link layers in multi-hop wireless networks. Reliable Minimum Energy Routing (RMER) and Reliable Minimum Energy Cost Routing (RMECR) are proposed for networks in which either hop-by-hop or end-to-end retransmissions ensure reliability. In mobile ad hoc networks, due to unreliable wireless media, host mobility and lack of infrastructure, providing secure communications is a big challenge in this type of network environment. In present work to ensure the security in unreliable wireless communication the cluster based topology scheme is used, to obtain confidentiality and authentication of nodes hash function and MAC (Message Authentication Code) techniques are used.
