Peer-To-Peer (P2P) and Mobile Ad hoc Networks (MANETs) share the same key concepts of self-organization and decentralization, and both aim to provide connectivity in a completely decentralized manner. Routing algorithms for MANETs can potentially benefit from the combination with P2P overlay routing algorithms. Some efforts have been made to integrate P2P overlay into MANETs, but all work is based...
In Mobile Ad-Hoc NETwork (MANET) there are many uncertainties like topological changes, number of nodes, mobility etc. Since the design of routing protocol is carried out by considering a particular environment, no existing routing protocol performs well for all possible environments and requirements. This paper proposes an adaptive protocol selector for MANET which helps in selecting an optimum routing...
We describe and verify convergence properties of our forced-based genetic algorithm (FGA) as a decentralized topology control mechanism distributed among software agents. FGA uses local information to guide autonomous mobile nodes over an unknown geographical terrain to obtain a uniform node distribution. Analyzing the convergence characteristics of FGA is difficult due to the stochastic nature of...
Due to the infrastructure-less mode of operation the mobile ad hoc networks have received significant research attention in recent years. They can be of immense use in case of emergency situations such as in relief operation, battlefield etc. Due to the highly dynamic nature, constantly changing topology and limited transmission range of the mobile nodes, routing in these networks is considered a...
Ad-hoc wireless network is a collection of wireless mobile nodes forming a temporary network without any centralized administration. A typical paradigm of wireless networks, such as mobile ad hoc networks (MANETs), comprise a number of mobile nodes that can organize freely but need mutual cooperation for information exchanges. However, such networks also face several important challenges such as resource-limitation,...
Topology control algorithms in mobile ad-hoc networks aim to reduce the power consumption while keeping the topology connected. These algorithms can preserve network resources and increase network capacity. However, few efforts have focused on the issue of topology control in presence of node mobility. One of the notable mobility aware topology control protocols is the ldquomobility aware distributed...
An innovative and scalable routing scheme for mobile ad-hoc networks (MANETs) is proposed, taking into account aspects such as quality of service (QoS) and resiliency. These issues are tackled by using a robust routing scheme in conjunction with a dynamic cell deferred routing strategy. This approach consists in dividing the network into cells which maintain different and sufficient topology views,...
In a mobile ad-hoc network, network topology changes dynamically due to mobility of computers, battery consumption and failure of mobile computers. Until now, many ad- hoc routing protocol tolerating such changes of network topology have been proposed. Here, all data messages are forwarded by all mobile computers included in a message transmission route detected by an ad-hoc routing protocol. No intermediate...
Mobile ad-hoc network (MANET) basically, consists of collection of mobile hosts incorporating wireless interfaces. These mobile nodes forms a transitory autonomous network and do not base on fixed infrastructure or central administration, rather they work on the principle of self-organized interconnections among mobile nodes. The idea at the core of the MANET technology is that while in movement when...
The next generation communication systems will provide high quality multimedia services in a flexible and efficient manner. As an extension of next generation networks, Mobile Ad Hoc Networks (MANETs) have attracted significant attention amongst researchers. Nodes in a MANET have limited battery power. Hence, ad hoc routing protocols ought to be energy conservative to support real-time multimedia...
Lots of real-world complex networks have recently been discovered scale-free characteristic, which the degree distributions of those networks display power-law distribution. The properties of mobile ad-hoc network and the conception of scale-free network are introduced firstly. Then, we focus on the inherent mechanisms of scale-free characteristic in ad-hoc networks. And the influence of scale-free...
A mobile node needs to be configured with a unique IP address. It has been seen that address autoconfiguration is a suitable technique in MANETs because of high mobility of nodes. Extensive survey of previous autoconfiguration related schemes reveal the need for reducing DoS attack, security breaches and improving DAD, QoS and overall performance. This paper also presents a critical study of mobility...
Both Peer-To-Peer (P2P) and mobile ad-hoc networks (MANETs) aim to provide seamless connectivity and services in a dynamic and decentralised environment. These two technologies, if unified, may be able to realise MANETs as a viable commercial technology and will enable the development of widespread distributed applications for MANETs. The push towards wireless ubiquitous computing means that service...
In building a real-life mobile ad-hoc network (MANET), network emulation has been appraised as an efficient approach for testing the real implementations of routing algorithms and protocol stacks. Most existing MANET emulators can hardly support both real-time scene construction for proof-of-concept test and real-time traffic recording for performance evaluation simultaneously. They also lack the...
