Routing in mobile Ad Hoc Networks

A Mobile Ad Hoc Network (MANET) is built on the fly where a number of wireless mobile nodes work in cooperation without the engagement of any centralized access point or any fixed infrastructure. Two nodes in such a network can communicate in a bidirectional manner if and only if the distance between them is at most the minimum of their transmission ranges. When a node wants to communicate with a node outside its transmission range, a multihop routing strategy is used which involves some intermediate nodes. Because of the movements of nodes, there is a constant possibility of topology change in MANET. Considering this unique aspect of MANET, a number of routing protocols have been proposed so far. This chapter gives an overview of the past, current, and future research areas for routing in MANET. In this chapter we will learn about the following things: - The preliminaries of mobile ad hoc network - The challenges for routing in MANET - Expected properties of a MANET routing protocol - Categories of routing protocols for MANET - Major routing protocols for MANET - Criteria for performance comparison of the routing protocols for MANET - Achievements and future research directions - Expectations and realit

Structured Peer-to-Peer Overlay Deployment on MANET: A Survey

There are many common characteristics between Peer-to-Peer (P2P) overlay networks and Mobile Ad-hoc Networks (MANET). Self-organization, decentralization, dynamicity and changing topology are the most shared features. Furthermore, when used together, the two approaches complement each other. P2P overlays provide data storage/retrieval functionality, and their routing information can complement that of MANET. MANET provides wireless connectivity between clients without depending on any pre-existing infrastructure. The aim of this paper is to survey current P2P over MANET systems. Specifically, this paper focuses on and investigates structured P2P over MANET. Overall, more than thirty distinct approaches have been classified into groups and introduced in tables providing a structured overview of the area. The survey addresses the identified approaches in terms of P2P systems, MANET underlay systems and the performance of the reviewed systems

Study and Literature or Research Survey of Routing Protocols and Routing Attacks in MANET with Different Security Technique in Cryptography for Network Security

Security is a most important issue on mobile ad hoc networks under various attacks. Mobile ad hoc network is categories of infrastructure less network. In this network each node connected without any central device and without topology. In this network routing protocols are classified into three different categories with different properties as reactive, proactive and hybrid protocols. Routing attacks in network defines a malicious node called attacker node, attacks on secret information in network. Routing attacks is classified into two categories internal and external attacks. External attacks can be divided into two categories as passive and active attacks. Most security techniques used in the network, can be classified into two categories symmetric called private and asymmetric called public key algorithm. In this research survey we study the various routing protocols, various routing attacks in mobile ad hoc networks (MANET) with different security techniques in cryptography
