Power aware and secure routing in mobile and ad-hoc networks

In Ad-hoc networking portable devices establish network for the communication and it is independent of a central infrastructure. However, due to the absence of central Infrastructure the devices in the ad-hoc network can move randomly gives rise to various kind of problems, such as routing and security. In Mobile and Ad-hoc Network (MANET) resources are very limited. Battery power of the node (Energy of the node) is an important resource for the MANET. The Ad-hoc On-demand Distance Vector Routing is most widely used protocol in MANET. AODV routing protocol creates the routes On-demand when any node has some data for the communication. In AODV routes breaks due to due to the node mobility and/or less battery power. Purpose of this work is to reduce the path breakage due to the less battery power by dynamically replacing the nodes with very less power by the nodes having sufficient amount of power. A distributed algorithm has also been developed to reduce the packet dropping attack in MANET which has been simulated on Network simulator-2 (NS-2) and demonstrated an increase in packet delivery ratio, throughput while decrease in average end-to-end delay as compared the basic AODV protocol.
