In this paper we have done performance comparisons of mobile ad hoc network’s protocol with its quality of service factors. It is seen that mobile ad hoc networks will be an integral part of next generation networks because of its flexibility, infrastructure less nature, ease of maintenance, auto configuration, self administration capabilities, and costs effectiveness. This research paper shows...

This paper evaluates quality of services for the mobile ad hoc network’s routing protocols. It is seen that mobile ad hoc networks will be an integral part of next generation networks because of its flexibility, infrastructure less nature, ease of maintenance, auto configuration, self administration capabilities, and cost effectiveness. This research paper shows comparative evaluation within mo...

The lack of any centralized infrastructure in mobile ad hoc networks (MANET) is one of the greatest security concerns in the deployment of wireless networks. MANET functions properly only if the participating nodes cooperate in routing without any malicious intention. However, some of the nodes may be malicious in their behavior by initially attracting a large amount of traffic and later on lau...

|Secure and eÆcient communication among a set of mobile nodes is one of the most important aspects in ad-hoc wireless networks. To ensure the security, several cryptography protocols must be implemented. Due to the resource scarcity in wireless networks, the protocols must be communication eÆcient and need as less computational power as possible. To secure the group broadcasting in wireless net...

Topology control in mobile ad-hoc networks allows better spatial reuse of the wireless channel and control over network resources. Topology control algorithms tend to optimise network power usage by keeping the topology connected. In this paper, we provide an overview of a range of centralised and distributed topology control algorithms proposed in literature. We also provide a comparison of th...

The Mobile Ad-hoc Networks are wireless networks that have no fixed infrastructure. There are no fixed routers-instead each node acts as router and forwards traffic from other nodes. Since the nodes in a MANET are highly mobile, the topology changes frequently and the nodes are dynamically connected in an arbitrary manner. This work focuses on reliable data packet forwarding in ad hoc networks ...

A mobile ad hoc network (MANET) is a collection of wireless mobile hosts forming a temporary network without the aid of any stand-alone infrastructure or centralized administration. Mobile Ad-hoc networks are self organizing and self-configuring multichip wireless networks where, the structure of the network changes dynamically. A routing protocol in MANET should fairly distribute the routing t...

In the recent years, the technology of wireless ad-hoc networks has gained a lot of importance. MANET is a special case of ad-hoc wireless networks. Mobile nodes have small batteries with limited power. Large number of sensor nodes in MANET makes it impractical to replace sensor node batteries. Thus the life time of Mobile nodes is an important attribute of wireless ad-hoc networks. The life ti...

Orthogonal Frequency Division Multiplexing (OFDM) is the physical layer in emerging wireless local area networks that are also being targeted for ad hoc networking. OFDM can be also exploited in ad hoc networks to improve the energy performance of mobile devices. It is important in wireless networks because it can be used adaptively in a dynamically changing channel. This study gives a detailed...

Mobile ad-hoc networks (MANET) enable the communication of mobile wireless nodes without any pre-defined infrastructure. Therefore, they are predestined for future mobile applications. To use existing applications and to inter-operate with the world wide internet, ad-hoc networks have to use TCP/IP, which were not designed for mobile adhoc networks and yield poor performance when deployed in th...
