Optimized Link State Routing protocol, an ad-hoc routing protocol, has been popular in wireless devices running on Linux operating system for quite some time. In this project we have outlined the process of preparing Android devices for ad-hoc networking, a way to overcome limitations of the OS for continuous UDP communication, ensure all devices communicate on the same wireless Wi-Fi SSID, Cell-ID, subnet and finally implement the Optimized Links State Routing (OLSR) in Android Operating System using Google Nexus 7 devices. Using the code base from ProjectSPAN, an open source project, OLSR protocol has been ported to Android Nexus 7 devices. The core application is divided into two major sections, MANET and OLSR. Mobile Ad-hoc Network portion of the code takes care of setting up the device for ad-hoc mode communication, firewall and peripheral setup while OLSR portion of the code maintains the neighbor tables, MPRs and routing. The project also describes the process by which a device is prepared to run low level custom codes in Android operating system. The OLSR implementation has been successfully tested with three nodes test bed, demonstrating the multi-hop ad-hoc networking capabilities of this wireless routing protocol. With the aid of the Android’s graphical interface the application is able to exhibit the dynamic nature of the OLSR protocol. As nodes and neighbors in the network moves around with respect to time and relative location, OLSR protocol is able to form new neighbors and elect Multipoint Relay in real time.

Mobile Ad hoc Network is a collection of mobile nodes in which the wireless links are frequently broken down due to mobility and dynamic infrastructure. Routing is a significant issue and challenge in ad hoc networks. In Mobile ad hoc network, due to mobility of nodes network topology change frequently and thus, routing become challenging task to transfer the data from source to destination. A variety of routing protocols with varying network conditions are analyzed to find an optimized route from a source to some destination. This paper is based on performance comparison of two popular mobile ad-hoc network routing protocols using simulator i.e. DSR, ADOV. On the network simulation platform, a systematically simulation and research has been carried out on the performance of two routing protocols, and how the network environments impact on the performance of routing protocol.

There are a lot of speculations going on about the interests for privacy in mobile network. Many research works have been proposed in the aspect and these works concentrate more on the anonymity part and there are quite a few implementations of these research works on some applications. Ad hoc routing protocols must have provision for both anonymity providing nature and restriction of information collection from unauthorized nodes. Till recent times, there are a number of ad hoc routing protocols that have been introduced. But, they have lack security features or authentication features or in some cases both. The lack of proper security features leads to a state of vulnerability which at any given point, will act as a threat element. In this paper, we propose Security Mandated Analytics based Route Processing with Digital Signature protocol [SMARPDS]. It is an anonymous and authentication providing routing protocol in Mobile Ad hoc network. In addition, routes are discovered based on analytics done on the node and its present location in the network. SMARPDS provides authentication during the route discovery and transmission process by employing digital signatures on node front and also on packets front.

Secured Routing

Mobile Ad hoc Network (MANET) is a group of wireless mobile nodes that dynamically creates a network without the support of central management. The mobile hosts of MANET network are not restricted to move freely in any direction and thus linking with any other mobile host can be easily done. Without giving any notification to other hosts in the network, they can be switched on or off. Each mobile host must forward traffic, unrelated to its own use and therefore acts as a router. Because of the mobility of wireless nodes, each node must have the capability of managing an autonomous system, or a routing function without requiring any centralized administration. This mobility and autonomy of the wireless nodes along with the transient nature of the end hosts and intermediate host in a communication path creates a dynamic topology of the network. These mobile hosts are connected in an arbitrary manner and as they are highly mobile, the topology changes take place frequently. The rate of change is based on the velocity of the nodes and the challenge is these devices are small and the available transmission power is limited. In this Trust Based Secured Routing Protocol for MANET (TSRPM), certain changes have been made in the design of secure ad hoc routing protocols. First, a modified Diffie Hellman algorithm is implemented; secondly a trust based model has been developed.

Optimized Link State Routing

Abstract In the last recent years, the number of wireless devices has been growing and the security challenges increases too. Mobile Ad hoc Network (MANET) considers as a part of wireless network that connects mobile devices by using wireless channels without infrastructure. MANET use specific protocols to ensure the connectivity and exchange data between the source and destination. Optimized Link State Routing Protocol (OLSR) is a table-driven protocol that keep the route to all destination at any times, unfortunately it can be affected by many active routing attacks that reduce its performance by dropping the exchange packets or stopping the forward of data. In this paper we present a new approach to detect any active routing attacks by using the concept of Shapiro-Wilk test. Our method of detection is easy to implement and does not require any modification in the standard version of OLSR routing protocol as we will demonstrate by NS-3 simulations the detection of Black hole, Worm hole and Node isolation attacks that consider as most known attacks in MANET. A real experience is done by creating a small ad hoc network that connect six wireless devices by using OLSR protocol and finally we detect the presence of an active routing attack by applying our proposed method.

Real World Problems

In this time of instant units, Mobile Ad-hoc Network(MANET) has become an indivisible part for transmission for mobile devices. Therefore, curiosity about study of Mobile Ad-hoc Network has been growing because last several years. In this report we have mentioned some simple routing protocols in MANET like Destination Sequenced Distance Vector, Active Source Redirecting, Temporally-Ordered Redirecting Algorithm and Ad-hoc On Need Distance Vector. Protection is just a serious problem in MANETs because they are infrastructure-less and autonomous. Principal target of writing this report is to handle some simple problems and security considerations in MANET, operation of wormhole strike and acquiring the well-known routing protocol Ad-hoc On Need Distance Vector. This short article will be a great help for the people performing study on real world problems in MANET security.
