Mobile ad-hoc networks (MANETs) are autonomous distributed networks, where mobile nodes communicate with each other using wireless links. Since the communication is done by wireless links, it is difficult to grasp how the packets flow between communication nodes. It becomes even more difficult when the number of nodes is increased. In our previous work, we proposed a visualization system for MANET...
Network management is a critical component of every network manager''''s job responsibility. This job gets more complicated as the complexity of the network grows. This complexity can be in the form of different manufacturers of deployed devices or added tiers to the network, such as an Ad Hoc Network or a Wireless Sensor Network. Automating, or semi-automating, the data analysis required in network...
Future networks are expected to become more complex and dynamic than today's networks. A centralized approach for network management is not able to deal with such complexity and dynamics, and will then introduce scalability problems. The concept of In Network Management (INM), where each INM entity (a network node) has the autonomy to self-govern its behavior, is being researched as an alternative...
Mobile ad hoc networks (MANET) are characterized by low bandwidth, lossy links and by constant topology change. Many network management architecture and techniques were put forward to adapt to these environments. In this paper, an adaptive, free management architecture based on peer management domain was proposed, and a new method of peer management domain partition was mainly introduced, last a prototype...
Mobile ad hoc networks are networks of mobile hosts with wireless interfaces that can dynamically form a network without the aid of any pre-existing infrastructure or centralized administration. Since the network topology changes frequently, efficient adaptive routing protocols such as AODV, DSR, and NTP are used. Security is the one of the major issue in mobile ad hoc network some of the attacks...
Nodes in energy-efficient ad-hoc wireless networks can benefit more of new ad-hoc services, as well as, can support better new emerging ad-hoc applications. In this paper, we introduce an approach to achieve the energy efficiency based on both optimal transmission range and topology management of ad-hoc wireless networks. We derive the relationship between the optimal transmission range (optimal grid...
The advances on wireless mesh networks are shifting the communications paradigm, where users can benefit from their cooperation to exchange information and make use of the spectrum space, forming wireless neighbourhood communities where resources are shared and services are distributed. This paper presents a modular cross-layer community management architecture, which considers that communities are...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
Broadcasting is an effective means for disseminating information in wireless ad hoc networks. In this paper we propose a novel distributed broadcasting protocol in wireless ad hoc networks, which is based on an highly efficient metric for characterizing the importance of a node, with respect to its contribution in covering the local neighborhood. The protocol is reliable and achieves small communication...
