In recent years group-oriented services are one of the primary application classes that are addressed by Mobile Ad hoc Networks (MANET). To support such services, multicast routing is used. Multicast routing is the simultaneous delivery of data stream to multiple destinations without sending duplicate copies over any one link with the objective of resource optimization. It can significantly improve...
The mobility of nodes in a Mobile Ad hoc Network results in frequent changes of network topology making routing in MANETs a challenging task. The efficient routing protocols can provide significant benefits to mobile ad hoc networks, in terms of both performance and reliability. Many routing protocols for such networks have been proposed so far. Some studies have been reported in the literature evaluating...
Security has become important to mobile ad hoc networks (MANETs) due mainly to their use for many mission and life-critical applications. However, the broadcast nature of inter-node communications and node mobility in MANETs make it very challenging to secure MANETs. Moreover, their constantly changing topology causes network node density and neighbor relationships to change dynamically. This paper...
The topology of a delay tolerant network (DTN) over time has been modeled by a space-time graph. However, the mobility of nodes, such as buses, may not be completely predictable due to factors such as traffic load, road condition, the number of passengers getting on and off the buses, and the operations of traffic lights. In this paper, we adapt the space-time graph by augmenting each horizontal edge...
Mobile ad hoc networks are increasingly finding their existence in the marketplace heading to a new paradigm of pervasive computing. However there are many areas open to research in the field. Due to node mobility resulting in an ever-changing network topology, conventional routing methods cannot be applied in MANETS. Therefore, this is one of the core areas of research. Researchers are challenged...
Due to node mobility and dynamic network topology, service compositions in ad hoc networks become unreliable. Improving reliability has been a research topic in service composition and ad hoc networks, and some work has considered minimizing disruption service composition and recovery in ad hoc networks. Backup service composition is a good choice for centralized network and some work have already...
In mobile wireless IP networking domains (i.e., MANETs), the network topology may be frequently changing due to node mobility. Under such network dynamics, simulation has shown that the OSPF routing protocol performs poorly (e.g., increased overhead and data loss), but can be modified with dasiaMANET extensionspsila to better its performance. To provide complementary validation of these observations,...
The performance of routing protocols in a mobile ad hoc network (MANET) is related to the network topology and nodes mobility. In order to ensure good performances of routing protocols in MANET, it is necessary to take into account the mobility criterion when choosing best routes in the network. In this paper, we propose a new measure of the network mobility which is relative and lightweight. Relative...
In this paper we focus on the problems of maintaining ad hoc network connectivity in the presence of node mobility whilst providing globally efficient and robust routing. The common approach among existing wireless ad hoc routing solutions is to establish a global optimal path between a source and a destination. We argue that establishing a globally optimal path is both unreliable and unsustainable...
