Book Description
Multicasting is all the rage these days for its provision of easy access to one connection instantly for everyone, on demand. Consider, in the last couple of years, multicasting has shown the promise of efficiently supporting a variety of applications that are characterized by a closed degree of synergism, typical for many ad-hoc applications currently being worked out. Within the wired networking realm, there exist well established solutions for routing problems to offer an efficient multicasting service. As the nodes go wireless and the notion of mobility of the nodes becomes part of the routing problem, those well established solutions need thorough reworking to provide a fairly high Quality of Service (QOS) in the new environment. This thesis analyzes the performance of a multicast protocol for ad-hoc networks: On Demand Multicast Routing Protocol (ODMRP). We implemented and modified ODMRP to analyse variants of the protocol. This work concerns itself with improving the performance of multicasting service in ad hoc networks using the mesh structure of ODMRP. ODMRP builds and maintains a mesh based on soft state. Our results show that ODMRP's characteristic high overheads could be curtailed down to a reasonable level without losing much in terms of throughput and packet delivery ratio.

Book Description
Mobile wireless ad-hoc networks (MANETs) are being designed to be a key element in future battlefield communications, as well as a supplement to cellular networks. As a consequence of rapid changes in the topology of the network, routing packets in MANETs is a challenging task that has attracted considerable attention. However a comprehensive performance evaluation of routing protocols remains an open problem. This dissertation proposes a novel methodology for the performance evaluation of routing protocols for MANETs. The method is based on a "Divide and Conquer" approach and it provides a systematic and disciplined way to evaluate the performance of routing protocols. The full routing system is decomposed into components (subsystems). Performance models are developed for each component. Then, the performance model of the full system is the interconnection of the performance models of the components. The component based approach makes practical the performance evaluation of routing protocols, by allowing researchers to reuse a subset of the previous developed models to evaluate the performance of new ideas.

Book Description
Ad-hoc networks are the particular type of networks, which are established by using more than one node in a specific arbitrary way to connect each other. These types of network systems can works without the fixed infrastructure for networks. The special feature which tries to makes their deployment quick and in the easy way. An Ad-hoc network can be utilize to provide network facilities in the places, where not to possible to form a fixed network, and where it is a cost effective to implement fixed network. The rapid implementation in the areas without the infrastructure which is often implies that the network users must explore an area and also form teams that in turn coordinate between themselves to create a specific task force or a nice mission in network simulation, also we can have individual random mobility and group mobility and also motion along with preplanned routes. Mobility model can be have major effect on the selection of a routing technique can then effect performance.

Book Description
This thesis presents a simulation and performance evaluation analysis of the various routing protocols that have been proposed for the Mobile Ad Hoc Network (MANET) environment using the Network Simulator-2 (NS-2) tool. Many routing protocols have been proposed by the academic communities for possible practical implementation of a MANET in military, governmental and commercial environments. Four (4) such routing protocols were chosen for analysis and evaluation: Ad Hoc On-demand Distance Vector routing (AODV), Dynamic Source Routing (DSR), Destination-Sequenced Distance Vector routing (DSDV) and Optimized Link State Routing (OLSR). NS-2 is developed and maintained by the University of Southern California's Information Sciences Institute (ISI). Leveraging on NS-2 s simulation capabilities, the key performance indicators of the routing protocols were analyzed such as data network throughput, routing overhead generation, data delivery delay as well as energy efficiency or optimization. The last metric is explored, especially due to its relevance to the mobile environment. Energy is a scare commodity in a mobile ad hoc environment. Any routing software that attempts to minimize energy usage will prolong the livelihood of the devices used in the battlefield. Three important mobility models are considered, namely, Random Waypoint, Manhattan Grid, and Reference Point Group Mobility. The application of these three models will enhance the realism of simulation to actual real life mobility in an urban or military setup scenario. The performance of the routing protocols in varied node density, mobility speed as well as loading conditions have been studied. The results of the simulation will provide invaluable insights to the performance of the selected routing protocols. This can serve as a deciding factor for the U.S. Department of Defense (DoD) in their selection of the most suitable routing protocols tailored to their specific needs.
