Wireless mesh backbones (WMBs) provide promising solutions for future networking strategies. Due to the mesh nature and thus the resource restrictions of such backbones the integration of mobility aware preloading mechanisms is essential for QoS provisioning, especially in environments with high mobility clients. This paper presents a novel concept, called mobility-aware forwarding in advance (MAFIA),...
The multicast routing model is set up by hybrid routing protocol, Aiming at the mobile network topology and the characteristics of multicast routing based on QoS. A multicast tree meeting the QoS constraints, consumption tend to a minimum and stable form is set up based on ant colony algorithm. Experiments show that the algorithm has a better performance than the other algorithm.
The ad hoc network is a non-infrastructure mobile network that consists of many mobile nodes. Since the nodes have a mobility features in ad hoc network, the ability of communication between the nodes is limited by nodespsila power. The power consumption and bandwidth of each mobile node becomes an important issue and needs to be addressed. The paper discusses the energy efficient routing problem...
Mobile ad hoc networks (MANET), which comprise of mobile nodes connected wirelessly, are emerging as a very important technology for future generation of wireless mobile and ubiquitous computing. MANETs are being used in numerous application domains from emergency rescue and relief to wireless sensor networks. To support real-time communications (such as audio and video) over MANETs, new quality of...
A Mobile Ad hoc NETwork (MANET) consists of a collection of mobile nodes. As MANETs are gaining popularity day-by-day, new developments in the area of real time and multimedia applications are rising as well. Such applications require Quality of Service (QoS) evolving in terms of the constraints such as bandwidth, end-to-end delay, jitter and energy. QoS provisioning for MANET can be achieved over...
In this paper, we investigate the issues of survivability and efficiency in a heterogeneous mobile ad hoc network (MANET) and Sensor network as a combined network where the communications is achieved using a mixed MANET and Sensor Network, referred to as SMANET for supporting mission critical applications. Using the cluster managed SMANET where, heterogeneous nodes with different capabilities and...
This paper explores the attributes, layering models and objective functions in cross layer designs for mobile ad hoc wireless networks by taking all the statistical characteristics and constraints from the physical (PHY) layer, media access control (MAC) layer and network (NET) layer into consideration. This paper reviews the entire network optimization across all the PHY/MAC/NET layers. At the PHY...
