Solving consensus in wireless ad hoc networks has started to be addressed in several papers. Most of these papers adopt system models similar to those developed for wired networks. These models are focused towards node failures while ignoring link failures, and thus are poorly suited for wireless ad hoc networks. The HO model, which was proposed recently, does not have this drawback. The paper ...

Ad hoc networks might be a disruptive technology in the mobile telecommunication industry. They are based on technologies like 802.11x and Bluetooth and range from wide area solutions to Personal Area Networks. Although they may not substitute current infrastructure in the near future they may threaten the dominant position of mobile operators enabling other players within the mobile value syst...

Ad hoc networks are wireless, infrastructure less, multi-hop, dynamic network established by a collection of mobile nodes which provides significant features to the modern communication technologies and services. In ad-hoc networks, clustering is an important and familiar technique to divide the large network into several sub networks. According to the dynamic topology the clustering is conside...

VANETs (Vehicular Ad hoc Networks) are highly mobile wireless ad hoc networks and will play an important role in public safety communications and commercial applications. Routing of data in VANETs is a challenging task due to rapidly changing topology and high speed mobility of vehicles. Conventional routing protocols in MANETs (Mobile Ad hoc Networks) are unable to fully address the unique cha...

Previous analysis of collision avoidance in ad hoc networks with hidden terminals has focused on senderinitiated schemes, like the IEEE 802.11 distributed coordination function. This paper presents analytical modeling of receiver-initiated collision avoidance schemes in multi-hop ad hoc networks. Our analysis shows that receiver-initiated schemes can offer substantial improvements over senderin...

A wireless network is a growing technology that allows users to access services and information electronically, irrespective of their geographic locations. Wireless network can be classified in two types: infrastructure network and infrastructure less (ad hoc) network. Mobile ad hoc network is an infrastructure less network without any central coordination point. Mobile ad hoc networks are char...

Wireless multi-hop ad hoc communication networks represent an infrastructure-less and self-organized generalization of todays wireless cellular networks. Connectivity within such a network is an important issue. Continuum percolation and technologydriven mutations thereof allow to address this issue in the static limit and to construct a simple distributed protocol, guaranteeing strong connecti...

Infrastructure-based wireless networks have base stations (access points). Advantages over Ad-hoc networks : efficiently utilize network resources. single-hop routes, results in : lower delay and loss higher data rates Examples : Wireless LANs, paging systems, and cellular phone systems.

Ad hoc networks are characterized by multi hop wireless connectivity, frequently changing network topology and the need for efficient dynamic routing protocols. This report compares the performance of MANET routing protocol such as Ad-hoc On Demand Distance Vector (AODV), LocationAided Routing (LAR1) and Wireless Routing Protocol (WRP) protocol at different Simulation time using a parallel disc...
