Under the Guidance of  Prof. Sumathy S (VIT University) ,I and my friend  Sri Harsha E worked  in NS2 and MANET for 6 months. These intensive days result in publishing 2 papers on analysis of Multicast Routing Protocols and Genetic Algorithm.

SURVEY OF GENETIC BASED APPROACH FOR MULTICAST ROUTING IN MANET


ABSTRACT:
An independent, self-governing group of mobile wireless hosts communicate through wireless links by forming a temporary network (Mobile Ad-hoc Network) in a dynamic manner without any fixed and centralized infrastructure. Since the nodes in MANET are not stationary, same path may not be taken always for routing between the sender and the receiver(s). So, routing in such situation is a complicated task. In addition, the resources of the wireless nodes are limited. With the intention of saving the resources of the nodes in the network, multicasting can be used instead of multiple unicast data transmissions whenever a node needs to send same data in parallel to several destinations. The grouporiented services are the primary ones that support today’s need and trend of communication. In recent years, such services are provided with the help of MANETs. The residual energy of the battery of a mobile node is finite (before recharging is done), which is a constraint while developing multicast routing protocols. Genetic Algorithm (GA) presents an improved solution for the multi-constrained multicast routing problem. By choosing proper fitness function and values for metrics such as initial population size, crossover and mutation that closely relates to the chosen scenario, the genetic algorithm optimizes the routes in terms of selected metrics. This paper focuses to provide a survey and analyses the categories of multicast routing protocols. In addition, this also covers the details of the application of genetic approach in finding multicast routes.

Analysis of Multicast Routing Protocols: Puma and Odmrp

ABSTRACT

In general, Wireless communication is defined as sharing of information between one or more systems through wireless links. Wireless networks can be categorized into two different modes as infrastructure based and infrastructure less. Infrastructure based mode is the most common use wireless mode for the end user loop. Infrastructure less mode also called as the Ad hoc mode relies on wireless communications without any fixed infrastructure. Infrastructure based networks are characterized by their use of access points (AP), or base stations. The most known example of infrastructure based wireless network is GSM and more recently, Wi-Fi. Ad Hoc networks introduce a new way of communication. An ad hoc network is a collection of wireless mobile nodes that dynamically functions as a network without the use of any existing infrastructure and centralized administration. Mobile Ad-hoc networking (MANET), an emerging field of wireless networking is an autonomous system of wireless mobile hosts, connected by wireless links that dynamically create a temporary network and establish an infrastructure less network. The topology of the network may change frequently and unpredictably. Multicast routing has been widely applied in mobile ad hoc networks (MANETs), to support different group oriented applications like video conferencing, interactions with Special interest groups etc., efficiently. This paper presents the comparative analysis of two multicast routing protocols, PUMA and ODMRP.
