Modified Adhoc on Demand Routing Protocol in Mobile Ad hoc Network

Abstract

In Ad hoc network there no any central infrastructure but it allows mobile devices to establish communication path.Since there is no central infrastructure and mobile devices are moving randomly ,gives rise to various kinds of problems, such as security and routing. here we are consider problem of routing. Routing is one of the key issues in MANET because of highly dynamic and distributed nature of nodes. Especially energy efficient routing is most important because all the nodes are battery powered. Failure of one node may affect the entire network. If a node runs out of energy the probability of network partition- ing will be increased. Since every mobile node has limited power supply, energy depletion is become one of the main threats to the lifetime of the ad hoc network. So routing in MANET should be in such a way that it will use the remaining battery power in an efficient way to increase the life time of the network. In this thesis, we have proposedModified Adhoc on Demand Routing (MAODV) which will efficiently utilize the battery power of the mobile nodes in such a way that the network will get more lifetime. Multiple paths are used to send data and load balancing approach is used to avoid over utilized nodes. Load balancing is done by selecting a route which contains energy rich nodes.
