Within the last decade, the use of wireless technologies has become more prevalent. Wireless networks have flexible architectures with data transferred via radio waves and can be divided into two categories; infrastructure-based wireless networks and mobile ad hoc network. The mobile ad hoc network (MANET) is an autonomous system which can be dynamically built without preexisting infrastructure...

This paper presents Chameleon, a novel anonymous overlay network for mobile ad hoc environments. As far we know, Chameleon is the first lowlatency anonymous overlay network applied in a mobile ad hoc setting. It was designed with the special characteristics of mobile ad hoc networks in mind, such as limited battery lifetime, user mobility and vanishing nodes. In this paper, we also evaluate Cha...

Wireless ad-hoc networks have gained a lot of importance in wireless communications. Wireless communication is established by nodes acting as routers and transferring packets from one to another in ad-hoc networks. Routing in these networks is highly complex due to moving nodes and hence many protocols have been developed. Mobile ad hoc networks are networks without fixed infrastructure. The mo...

The growing availability of networked mobile devices has created a vast collective potential of unexploited resources. Grid computing with its model of coordinated resource sharing may provide a way to utilize such resources that are normally distributed throughout a mobile ad-hoc network. In this paper, we explore the challenging operation of Grid computing in mobile ad-hoc networks which are ...

A mobile ad hoc network is comprised of mobile hosts that can communicate with each other using wireless links. It is also possible to have access to some host in a fixed infrastructure depending on the kind of the mobile ad hoc network. Mobile ad hoc networks can be realized by different networks such as body area network (BAN), vehicular ad hoc network (VANET), wireless sensor network (WSN). ...

Wireless ad-hoc networks has now become one of the most vibrant and active field of communication and networks. Due to lack of a defined central authority, MANETs are more vulnerable to security attacks and thus security is essential requirement in MANET as compared to the wired network. The nature and structure of MANET makes it attractive to various types of attackers. In this paper the princ...

Nowadays, the world gets more and more mobile in such a way that communication services are desirable anytime and anywhere. In this context, Mobile wireless ad-hoc networks, including mobile ad-hoc networks (MANETs) and Mesh-Networks, are systems of nodes that interconnect in a dynamical self-organized way providing an attraction especially during mission-crucial or time-crucial applications, f...

Mobile Ad hoc networks (MANETs) are composed of mobile stations communicating through wireless links, without any fixed backbone support. In these networks, limited power energy supply, and frequent topology changes caused by node mobility, makes their routing a challenging problem. TORA is one of the routing protocols that successfully copes with the nodes’ mobility side effects, but it do...

Routing and multicasting in ad hoc networks is a matured research subject. Most of the proposed algorithms assume a physically flat network architecture with mobile hosts having homogeneous capability in terms of network resources and computing power. In practice however, this assumption often may not hold true since there exist various types of mobile hosts with different role, capacity, and m...
