Ad hoc networking allows portable devices to establish communication independent of a central infrastructure. The Integration of the MANETs and infrastructure networks such as Internet extends the network coverage and increases the application domain of the MANET. Communication between a mobile device in an ad hoc network and a fixed device on the Internet is achieved using gateways, which acts as...
Mobile ad-hoc networks, such as tactical networks, are frequently implemented using multiple subnets, or tiers, so that nodes in one tier can communicate to nodes in another tier only through gateways that can communicate in two of the tiers. The selection of the gateway nodes affects the robustness and performance of the connected subnets. This paper presents an algorithm for selecting gateways in...
In a large mission critical wireless ad hoc network, heterogeneous nodes with different capabilities and nodes from different organizations may be deployed within the same geographical area. This is typical for many mission critical applications such as military networks. For such applications, on one hand, a node from one organization may collaborate with the nodes from a different organization for...
Multicast communication over mobile ad hoc networks becomes popular. Dependable and scalable multicast routing protocol is required for large mobile ad hoc networks, even though network size and node mobility continue to increase. However, the data packet delivery becomes less dependable due to radio interference and frequent route breaks as the hop count between the source node and the multicast...
In recent years, various types of ad hoc routing protocols have been studied in the mobile ad hoc networks. Specifically, the clustering hierarchical routing algorithms have been developed to increase the system performance. Hierarchical structure has inevitably brought some drawbacks, maintaining the hierarchical structure needs more complicated cluster heads selection algorithm, which may result...
We introduce here a novel routing protocol for a class of reconfigurable wireless ad hoc networks. The main features of these ad hoc networks are increased nodes mobility, a larger number of nodes, and a large network span. We argue that current routing protocols do not provide a satisfactory solution for routing in this type of environment. We propose a scheme, called the link-state RAID routing...
This paper presents a cluster-based self-organizing algorithm for creating automatically ad-hoc networks including diverse wireless devices such as PDA, cell phones, laptops, wireless sensors, etc. In the proposed strategy each mobile device is represented by a multi-role agent, which generates a backbone among the devices within the environment based only on local interactions. During the operation...
In this paper we discuss the impact of proactive routing in comparison with a reactive routing approach in an environment where multiple communication technologies are used simultaneously. Therefore the Virtual Private Ad Hoc Networking platform will be introduced and used. A simulation environment is created and used to illustrate the outcomes with a simple scenario. Although many papers have been...
