  Wireless networks and the usage of mobile devices are becoming popular in recent days, especially in creating Ad-Hoc networks. There is thus scope for developing mobile systems, where devices take an active part of creating a network infrastructure and can actually be used to route data between networks. This research proposes to assess different models of the usage of static and JADE Mobile Agents to determine the best route through Ad-Hoc networks. The determination of this route is a complex one and requires research into the best metrics to identify the best path, such as memory capacity, network performance, processing capabilities, cost and so on. One model is to use a mixture of mobile and static agents to gather relevant information. These agents could perform important tests, which could be used to generate the best route through a network. This research looks at different models for the deployment of these agents, which balance the usage of static and JADE Mobile Agents. These are appraised in the terms of performance, reconfigurability and easy of installation.

  This study presents a novel multicast routing protocol for mobile ad-hoc wireless networks. The protocol, termed ODMRP (On-Demand Multicast Routing Protocol) is a mesh-based, rather than a conventional treebased, multicast scheme and uses a forwarding group concept (only a subset of nodes forwards the multicast packets via scoped flooding). It applies on-demand procedures to dynamically build routes and maintain multicast group membership. ODMRP is well suited for ad hoc wireless networks with mobile hosts where bandwidth is limited, topology changes frequently and power is constrained. We evaluate ODMRP`s scalability and performance.This ODMRP is put inside JADE Agents to improve functionality.

  Many potential applications of Mobile Ad hoc Networks (MANETs) involve group communications among the nodes. Multicasting is an useful operation that facilitates group communications. Efficient and scalable multicast routing in MANETs is a difficult issue. In addition to the conventional multicast routing algorithms, recent protocols have adopted the following new approaches: Overlays, backbone-based and stateless. These protocols are implemented within RETSINA agents. In this study, we study these approaches from the protocol state management point of view and compare their scalability behaviors. To enhance performance and enable scalability, we have proposed a framework for hierarchical multicasting in MANET environments. Two classes of hierarchical multicasting approaches, termed as domain-based and overlay-based, are proposed. We have considered a variety of approaches that are suitable for different mobility patterns and multicast group sizes. Results obtained through simulations demonstrate enhanced performance and scalability of the proposed techniques.
