We propose a complete design for a scope limited, multihop broadcast middleware, which is adapted to the variability of the ad-hoc environment and works in unlimited ad-hoc networks such as a crowd in a city, or car passengers in a busy highway system. We address practical problems posed by: the impossibility to set the TTL correctly at all times, the poor performance of multiple access protoco...

Many previous papers have pointed out that TCP performance in multi-hop ad hoc networks (MANETs) is sub-optimal. This is due to several TCP design principles that reflect the characteristics of wired networks dominant at the time when TCP was designed that do not hold in MANETs. Based on this evidence, several TCP variants have been proposed in the literature. However, little effort has been de...

The paper formally defines the problem of constrained Steiner tree (CST) in the context of wireless ad hoc networks. In contrast to wired networks, due to the broadcast nature of wireless communications, the notion of cost and delay is defined based on node, rather than link. By adapting the metaphor of Swarm Intelligence, the paper describes a distributed and asynchronous algorithm, termed CST...

Abstract. We propose a notion of extended dominating set whereby each node in an ad hoc network is covered by either a dominating neighbor or several 2-hop dominating neighbors. This work is motivated by cooperative communication in ad hoc networks where transmitting independent copies of a packet generates diversity and combats the effects of fading. In this paper we propose several efficient ...

Mobile Ad Hoc Networks (MANETs) is a self-configurable network of mobile nodes connected by wireless links to form an arbitrary topology and communicate to each other without the use of existing infrastructure. Complexities of routing between the nodes are increasing due to the highly dynamic nature of the mobile ad hoc network results in frequent change in network topology. The routing protoco...

A mobile ad-hoc network (MANET) is a characteristized by multi-hop wireless links, in the absence of any cellular infrastructure, as well as frequent host mobility. Existing on-demand multicasting protocols are categorized into tree-based and mesh-based strategies. In this paper, we propose a new on-demand multicast routing protocol, named spiral-fat-tree-based on-demand multicast protocol (SOM...

The groups of people that use an ad hoc network form a social network that exhibits small world properties. In this paper the impact of small world phenomena in application layer network on performance of ad hoc network is investigated. We show that small world properties have a big influence on the performance taking into consideration different routing protocols and network area shapes. In or...

Wireless multi-hop networks have attracted the attention of the research community in the last years. Two classes of wireless multi-hop networks are usually considered: mobile multi-hop networks, usually referred to as ad-hoc networks, and fixed multi-hop networks, usually referred to as wireless mesh networks (WMN). WMN are a promising solution to provide both indoor and outdoor broadband wire...

Mobile Ad hoc Network (MANET), a collection of nodes that form a multi-hop wireless network, is emerging as an important technology in the present and near future. MANETs are being used in a variety of applications from emergency rescue to sensor networks. With the expansion of real-time applications for this type of networks, the need for quality of service (QoS) support has become essential. ...
