Performance Evaluation of MANETs with Variation in Transmission Power using Ad-hoc on-demand Multipath Distance Vector Routing Protocol

With the evolution of dynamically changing network applications, for efficient, seamless and last mile connectivity Mobile Ad-hoc Networks (MANETs) provide a cost effective solution. The mobile nodes in MANETs are randomly connected and their location and functioning keeps on changing based on the situation and network application requirement. However, the nodes in MANETs are battery powered which is one of the limiting factors in their performance. However, seamless and longer duration connectivity depends upon the lifetime of individual nodes. The power consumption during transmission is the critical design issue in MANET's. This work involves the performance evaluation of a designed MANET scenario with variation in transmission power using Ad-hoc On-Demand Multipath Distance Vector (AOMDV) Routing Protocol (RP) at variable node configuration. The performance of designed MANET scenario is evaluated using several qualitative performance metrics for optimum performance using QualNet simulator.
