This paper studies the exact per node throughput capacity of a MANET, where the transmission power of each node can be controlled to adapt to a specified transmission range υ and a generalized two-hop relay with limited packet redundancy f is adopted for packet routing. Based on the concept of automatic feedback control and the Markov chain model, we first develop a general theoretical framework to fully depict the complicated packet delivery process in the challenging MANET. With the help of the framework, we are then able to derive the exact per node throughput capacity for a fixed setting of both υ and f. Based on the new throughput result; we further explore the optimal throughput capacity for any f but a fixed υ and also determine the corresponding optimum setting of f to achieve it. This result helps us to understand how such optimal capacity varies with υ (and thus transmission power) and to find the maximum possible throughput capacity of such a network for any f and υ. interestingly, our results show that increasing the transmission power of the nodes improves the capacity, which is the same as that proved in fixed networks

<p>The aim of this paper is to model the Portable Manager and allow it to aid in communication among Mobile Ad-hoc Networks (MANETs) carrying information across the mobile nodes in the network. In this article, Modeling Portable Manager aiding in the MANET Communication (MMAC) is proposed. The novelty is present in the use of node performance parameter called as α defined as the ratio of the packet received, packet loss and delay of the node which could be used for the next hop selection in the mobile ad hoc network. The Portable Manager (PM) is used to find out the relay node in the network. The working of the PM with a minimal number of nodes is analyzed and presented through the simulations in the network simulator.</p>
