This report examined the applications of MANET nowadays. The report not only reviews the pure general-purpose MANET, but also other specified MANETs: mesh networks, opportunistic networks, vehicular ad hoc networks and wireless networks. We can see that, although pure general-purpose MANET does not yet exist in the real world, the multihop ad hoc networking paradigm was successfully applied in ...

Multihop ad hoc wireless networks consist of mobile nodes that communicate with each other without any fixed infrastructure. The nodes in these networks are power constrained, since they operate in limited battery energy. Cooperative caching is an attractive solution for reducing network traffic and bandwidth demands in mobile ad hoc networks. Deploying caches in mobile nodes can reduce the ove...

The idea of virtual backbone routing for ad hoc wireless networks is to operate routing protocols over a virtual backbone. One purpose of virtual backbone routing is to alleviate the serious broadcast storm problem suffered by many exiting on-demand routing protocols for route detection. Thus constructing a virtual backbone is very important. In our study, the virtual backbone is approximated b...

In this paper we address the problem of secure multicast of data streams over a multihop wireless ad hoc network. We propose a key management protocol that aims at solving problems that are specific to ad hoc networks such as mobility, unreliable links, and multihop communication cost. The main idea is to have group members actively participate to the multicast group security therefore reducing...

Existing geographic routing algorithms face serious challenges due to location errors, nonplanarity issues and overhead of location service. To solve these issues, we propose Topological Cluster Based Geographic Routing that combines topology-based routing and geographic routing. It is a localized routing scheme where the geographic routing is performed on an overlay network of topological clus...

One wireless network architecture that has received a lot of attention recently is the mobile ad hoc network (MANET). It is attractive because the network can be quickly deployed without the infrastructure of base stations. One main feature of MANET is that mobile hosts may communicate with each other through a sequence of wireless links (i.e., in a multihop manner). While many routing protocol...

Mobile Ad hoc Networks (MANETs) are becoming very attractive and useful in many kinds of communication and networking applications. Due to the advantage of quick construction and numerical analysis of analytical modelling techniques, such as Stochastic Petri nets, Queueing Networks and Process Algebra, have been broadly used for performance analysis of computer networks. In addition, analytical...

Recent research ([12][15][19]) shows that the flooding mechanism (for topology update or route request) used in existing protocols for ad hoc wireless networks greatly degrades the network capacity. If we force the effective broadcasts of control packets happen in a small subset of hosts in the network, the protocol overhead caused by global flooding can be substantially reduced. This is the ba...
